Linking button to new page in Django not working - html

I have created an update view and am trying to link it to my form
but the button linking doesn't seem to be working at all
urls.py
path('uploadupdate/<int:upload_id>', UploadUpdate.as_view(), name='uploadupdate'),
template:
{% load static %}
<!DOCTYPE html>
<html>
<head>
<title>Manage uploads</title>
<link rel="stylesheet" href="{% static 'studyadmin/manageuploads_css.css' %}">
</head>
<body>
<table >
<tr class="main_row">
<th> Upload Name </th>
<th> Author Name </th>
<th> Type </th>
<th> Date </th>
<th> Edit </th>
<th>Edit Tags</th>
</tr>
<form >
{% csrf_token %}
{% for uploads in uploads %} <!-- shows all contents -->
<tr>
<th> {{ uploads.title}} </th>
<th> {{ uploads.author }} </th>
<th> {{ uploads.upload_type }} </th>
<th> {{ uploads.date_posted|date:"d M, Y" }} </th>
<th> <button href="{% url 'uploadupdate' uploads.upload_id %}" type="submit" class="edit" formmethod="POST">Edit</button> </th>
<th> <button href="#" type="submit" class="edittags" formmethod="POST" >Edit tags</button> </th>
{% endfor %}
</form>
</table>
</body>
</html>
views.py
class UploadUpdate(UpdateView):
form_class = UploadEditForm
template_name = 'studyadmin/upload_update_form.html'
queryset = Uploads.objects.all()
def get_object(self, queryset=None):
obj = Uploads.objects.get(upload_id=self.kwargs['upload_id'])
print(obj)
return obj
def form_valid(self, form):
upload = form.save(commit=False)
upload.save()
return redirect('/manageupload/')
I added the relevant code, I feel like its a small error but I can't seem to identify it since I'm very new to Django, any help would be appreciated!

You should refer to your app to use that URL because Django doesn't know to which app your URL name belongs to by default. So it'd be something like <button href="{% url 'appname:uploadupdate' uploads.upload_id %}" type="submit" class="edit" formmethod="POST">Edit</button>. Of course make sure that your project's URL Configuration includes your app's URLs. Hope it helps.
UPDATE
From the Django Documentation:
...
class ContactView(FormView):
template_name = 'contact.html'
form_class = ContactForm
success_url = '/thanks/'
def form_valid(self, form):
form.send_email()
return super().form_valid(form)
Notes:
FormView inherits TemplateResponseMixin so template_name can be used here.
The default implementation for form_valid() simply redirects to the success_url.
So you should edit your View.

dont do this in your forms , Use it for getting the Fields from the models and the view allows you to connect your forms directly with your page you can directly print our data in a page so there is an example :
My models i have Question and ansewer attribute :
------ models.py ------
class Question_cours(models.Model):
quest = models.CharField(max_length= 200 ) ---> question
rep = models.CharField(max_length = 20) ----> answer
--------- forms.py --------
class Form_question(forms.Form): /// important to make the same name fields
quest = forms.CharField()
rep = forms.CharField()
-------- view.py ----------
#-----------------------------------------------------------------------------
def add_question_cours(request):
form = Form_question()
if request.method == "POST":
form = Form_question(request.POST)
if form.is_valid() :
Question_cours.objects.create(**form.cleaned_data)
else :
print(form.errors)
return render(request , 'bootstrap/add_question.html',context)
#------------------------------------------------------------------------------
-----------urls.py------------
path('dfsdf',views.add_question_cours,name='add_question')
-----------------add_question.html----------
<form method="POST">{% csrf_token %}
<div class ="form-group">
{{ form.as_p}}
</div>
<button type =" submit" class="btn btn-danger ">
<i class ="fa fa-plus"></i>
</button>

Django: How to display specific object to specific user

I am new to django and working on a project where admin have to assign a team to manager and when ever admin assign a team to manager then it will be shown to that specific manager only.I have no idea how can i do this. Please if someone can help please help me.
here is my .html file for admin from where admin can assign team to manager.
<thead>
<tr>
<th>S No.</th>
<th>COMPANY NAME</th>
<th>TEAM MEMBER</th>
<th>EMAIL</th>
<th>ASSIGN TEAM</th>
</tr>
</thead>
<tbody>
{%for team in object%}
<tr>
<form id="form_id" method="POST" action = "{% url 'accept' %}">
{% csrf_token %}
<th scope="row"> {{ forloop.counter }}</th>
<td>{{team.company_name}}</td>
<td>{{team.team_member}}</td>
<td>{{team.email}}</td>
<td>
<select name="manager_{{manager.id}}">
{% for manager in managers %}
<option value ="{{manager.id}}">{{manager.name}}</option>
{% endfor %}
</select>
</td>
<td>
<input class="btn btn-raised btn-primary btn-round waves-effect" type="submit" value="Assign">
</td>
</tr>
{% endfor %}
here is my model for the team and manager:
class Create_Team(models.Model):
first_name = models.CharField(max_length= 50)
last_name = models.CharField(max_length= 50)
company_name = models.CharField(max_length= 100)
address = models.CharField(max_length= 1000)
state = models.CharField(max_length= 100)
city = models.CharField(max_length= 100)
status = models.CharField(max_length= 30)
class manager(models.Model):
name = models.CharField(max_length= 500)
designation = models.CharField(max_length= 500)
here is my views.py file for manager and from where the admin is accepting the request:
def accept(request):
obj= Create_Team.objects.filter(status='Accept')
managers = manager.objects.all()
if request.method == 'POST':
acc = manager()
manager_id = int(request.POST.get('manager', 1))
acc.manager = manager.objects.get(pk=manager_id)
return render(request, "admin/accept.html", {"object": obj, "managers": managers})
def superior(request):
return render(request, 'manager/index-3.html')
I want that whenever the admin will click on the assign button then that team will be displayed to that manager.Please help me.
There are several issues with your code.
There is no relation from the Create_Team to the manager model.
The name attribute on your <select> tags do not match the key you using to read from request.POST. manager_{{manager.id}} renders as manager_, so int(request.POST.get('manager', 1)) will always return 1.
The forms in your template do not contain the information which team you want to update.
You do not set the attribute selected on any <option>. As a consequence, the first choice will always be selected.
You are not updating any team in your view.
Let's address these issues.
1 - We fix the models by adding a ForeignKey from CreateTeam to Manager. Note that I've renamed the models, which is optional. If you decide to keep your names, adapt it accordingly.
# models.py
from django.db import models
class CreateTeam(models.Model):
first_name = models.CharField(max_length= 50)
last_name = models.CharField(max_length= 50)
company_name = models.CharField(max_length= 100)
address = models.CharField(max_length= 1000)
state = models.CharField(max_length= 100)
city = models.CharField(max_length= 100)
status = models.CharField(max_length= 30)
manager = models.ForeignKey('Manager', on_delete=models.SET_NULL, null=True, blank=True)
class Manager(models.Model):
name = models.CharField(max_length= 500)
designation = models.CharField(max_length= 500)
You have to pass two bits of information to the assign view: the id of the CreateTeam you want to assign and the id of the Manager you want to assign it to.
Note that the name attribute of form fields is the key in request.POST. These can be any string, just make sure it matches between form and view. It obviously makes life to give them an expressive name.
2 - Sending the id of the Manager is handled by the <select>. Just make sure the name attribute matching the key you use in your view.
3 - To send the id of the team, you could use a <button type="submit"> with a name and a value instead of the <input type="submit">.
<button class="btn btn-raised btn-primary btn-round waves-effect" type="submit" name="team" value="{{ team.id }}">Assign</button>
</td>
Alternatively, you could use a hidden field.
4 - Finally, you have to have to set the attribute selected on the correct <option> in your <select>. You can do that like this:
<option value="{{manager.id}}" {% if team.manager.id == manager.id %}selected{% endif %}
Here is the complete template:
<html>
<head></head>
<body>
<table>
<thead>
<tr>
<th>S No.</th>
<th>COMPANY NAME</th>
<th>TEAM MEMBER</th>
<th>EMAIL</th>
<th>ASSIGN TEAM</th>
</tr>
</thead>
<tbody>
{%for team in teams%}
<tr>
<form id="form_id" method="POST" action="{% url 'accept' %}">
{% csrf_token %}
<th scope="row"> {{ forloop.counter }}</th>
<td>{{team.company_name}}</td>
<td>{{team.team_member}}</td>
<td>{{team.email}}</td>
<td>
<select name="manager">
{% for manager in managers %}
<option value="{{manager.id}}" {% if team.manager.id == manager.id %}selected{% endif %}>{{manager.name}}</option>
{% endfor %}
</select>
</td>
<td>
<button class="btn btn-raised btn-primary btn-round waves-effect" type="submit" name="team" value="{{ team.id }}">Assign</button>
</td>
</form>
</tr>
{% endfor %}
</tbody>
</table>
</body>
</html>
5 - When receiving a POST request, you can assign the manager to the team.
That means you have to use the id values to get a CreateTeam instance and a Manager instance. Then you assign the Manager to createteam.manager and save the createteam object.
from django.shortcuts import get_object_or_404, redirect, render
from .models import CreateTeam, Manager
def accept(request):
teams = CreateTeam.objects.filter(status='Accept')
managers = Manager.objects.all()
if request.method == 'POST':
createteam_id = int(request.POST.get('team', 1))
manager_id = int(request.POST.get('manager', 1))
createteam = get_object_or_404(teams, pk=createteam_id)
createteam.manager = get_object_or_404(Manager, pk=manager_id)
createteam.save()
redirect('accept')
return render(request, "admin/accept.html", {"teams": teams, "managers": managers})
There are three things worth highlighting:
We use get_object_or_404 instead of Model.objects.get. As the name implies, it returns a 404 if no model can be found. This serves as a simple error handling for edge cases like a user manipulating the form or a manager being deleted while the user has the page open. This error handling could be improved to be more user-friendly, but it's a start.
get_object_or_404 can take a model or a queryset. We load the team instance from the filtered queryset teams. Otherwise, a user could manipulate a form and assign a manager to a team that has a status other than Accept.
After saving the team, we redirect to the accept page. This is good practice and ensures that a user can reload the page without seeing the do you want to resubmit this form dialog.
Finally, make sure that this view is really only accessible by the admin, e.g. by adding an appropriate user_passes_test decorator.

Django - Save checked checkboxes on reload

I am trying to save checked off checkboxes.
The issue I am having right now is that when I press the email button, the page goes blank and when I try to go back, it asks me if I want to "Confirm Form Resubmission". I also tried linking the same page back like this in the form tag:
<form action="{% url 'ordered_user_list' %} method="post">
Note that the email button shouldn't do anything except reload the same page, but have the boxes checked as before. Also, if I come back to it from a different page, it should still be checked off as before.
in html file
<form method="post">
<table class="table">
<tr>
<th></th>
<th><u>Last Name</u></th>
<th><u>First Name</u></th>
<th style="width: 30%"><u>Email</u></th>
<th><u>Phone</u></th>
</tr>
{% for user in object_list %}
<tr>
<td><input type="checkbox" name="emailList" value="{{user.id}}"></td>
<td> {{ user.lastName|capfirst }}</td>
<td><a href="{% url "user_info" user.id %}">{{ user.firstName|capfirst }}</td>
<td>{{ user.email }}</td>
<td>{{ user.phone }}</td>
</tr>
{% endfor %}
</table>
{% csrf_token %}
<input class = "btn btn-danger" type="submit" value="Email"/></form>
in View file
class OrderedUserList(ListView):
model = User
template_name = "Schedule/ordered_user_list.html"
def dispatch(self, *args, **kwargs):
if not self.request.user.is_authenticated() or (not self.request.user.admin and not self.request.user.volunteer_coordinator):
return forbidden()
checked = request.POST.get('emailList')
return super(OrderedUserList, self).dispatch(*args, **kwargs)
You can save the selections by setting a COOKIE(in your view) by using the 'set_cookie' command.You can then access this cookie within your session and get the values of selections wherever you want.But remember that 1)the cookie saves your selection as a single string so be careful about how you save your selections so it is easier to extract them later (using string split method) and 2)it has a downside that this will be a system-dependent solution as the cookie wont be accessible if you save a cookie on one device and try to login from some other device/system at the same time.Hope this helps....

Django: can "double" 'render_to_response' be unified into only one view?

I have defined two functions in views.py to obtain first prova.html with certain elementimenu and then, after clicking over one of them, I obtain again the page with elementimenu and elementi associated to elementimenu with the same id i.e.:
another_app.model.py
...
class ElementiTab(models.Model):
author = models.ForeignKey('auth.User', null=True, blank=False)
des = models.CharField(max_length=30)
x = models.FloatField()
y = models.FloatField()
res = models.FloatField(default=0)
created_date = models.DateTimeField(default=timezone.now)
...
And here the code that I like to get better:
views.py
from another_app.model import ElementiTab
def show_elementi(request):
elementimenu = ElementiTab.objects.all()
return render_to_response('homepage/prova.html',{'elementimenu': elementimenu, 'user.username': request}, context_instance = RequestContext(request))
def show_detail(request,id):
elementimenu = ElementiTab.objects.all()
detail = get_object_or_404(ElementiTab, pk=id)
return render_to_response('homepage/prova.html',{'elementimenu': elementimenu, 'detail': detail, 'user.username': request}, context_instance = RequestContext(request))
urls.py
...
url(r'^homepage/prova/$', views.show_elementi),
url(r'^show_detail/(?P<id>\d+)/$', views.show_detail),
...
prova.html
...
<div class="elementi">
{% for elementi in elementimenu %}
{{elementi.des}}
{% endfor %}
</div>
<div class="table-responsive">
<table class="table table-bordered">
<tr class="info">
<td width="35%" align="center"> NOME</td>
<td width="35%" align="center"> DATA CREAZIONE </td>
<td width="30%" align="center"> AUTORE </td>
</tr>
{% if detail %}
<div class="dettagli">
<tr>
<td>{{detail.des}}</td>
<td>{{detail.created_date}}</td>
<td>{{detail.author}}</td>
</tr>
{% endif %}
</div>
</table>
</div>
...
I had used this "trick" in show_detail view so that I can see elementimenu even after calling this function.
Is there a more elegant way to do this?
Yes, you can use the single view. Add the default None value for the id (or pk) argument:
def show_elementi(request, pk=None):
elementimenu = ElementiTab.objects.all()
detail = get_object_or_404(ElementiTab, pk=pk) if pk else None
return render(request, 'homepage/prova.html',
{'elementimenu': elementimenu, 'detail': detail})
And then map both urls to this view:
url(r'^homepage/prova/$', views.show_elementi),
url(r'^show_detail/(?P<pk>\d+)/$', views.show_elementi),

How can I take input from a text field in a Django page then update a SQL table with the response?

I am working on a site that will be used to clean up inactive Tableau workbooks. Logging into this site will allow my users to see their old workbooks and decide which ones to keep.
This is going to be accomplished by taking some simple text input from an HTML page, K for keep | D for delete.
The response from the user will then be stored as a Python variable that will go into an if then statement. The if then statement will basically update each row in SQL, adding either K or D to a column called "Marked_for_Deletion".
From there, a stored procedure will run, check that column, and delete all things marked with a D.
Is this feasible? If so, how would I go about pulling that input and making sure it gets added to the right column/row? If not, can you offer any suggestions on a substitute method I can use?
Thanks!
Edit: Here is the code for my table.
<table class="blueTable">
<thead>
<tr>
<th>Workbook Name</th>
<th>Deletion Deadline</th>
<th>Keep or Delete?</th>
</tr>
</thead>
<tbody>
{% for book in Workbooks %}
<tr>
<td>{{ book.name }}</td>
<td>{{ book.owner_name }}</td>
<td>
<label class="container" style="margin-bottom: 25px">
<input type="text" placeholder="(Enter K for Keep, D for Delete)">
</label>
</td>
</tr>
{% endfor %}
</tbody>
</table>
<form method="post">
{% csrf_token %}
<button type="submit" name="run_script">Submit</button>
</form>
</body>
</html>
I want to be able to pull the input from the last td tag and store it with the submit button below there.
I'm kind of late, but I hope it helps you out.

P.S. I'm not handling exceptions, messages, etc. You're just gonna have to figure it out yourself or open a new question.
