How to call in django index.html fle for "GET" "POST" method for get data from id (fields)? - html

Question

In django I have create query like wise if someone want information:
In district parameter select Pune, then output gives data for pune district only.
for example :
http:127.0.0.1/api/?district=Pune
htt:127.0.0.1:8000/?crop = groundnut
and so on.
Next,I want to create a Html page for my starting django page(index.html)
if I runserver http:127.0.0.1:8000/
display my html file , where Our models fields(paramter) is id and then user submit the question "if" condition will be trigger and searching information for that parameters.
like wise:
District = __________ submit
gives data only for selected district name only
also
Crop = ______________ submit
gives data only for selected crop name only
likewise run this query
http:/api/?crop=groundnut
if user choose crop name is groundnut,
if use choose crop name is guava, then http:/api/?crop=guava query will be run.
So,now I want to create index.html file multiple parameters works.(AND query will apply)
http:/api/district=Pune&crop=groundnut
So, I want to create html page which call to this query and its show me this type
Distrcit : ________ Crop : __________ submit
here is my models.py
from django.db import models
from mongoengine import Document, fields
class Tool(Document):
crop = fields.StringField(required=True)
district = fields.StringField(required=True)
def __str__(self):
return self.crop
def save(self,*args, **kwargs):
super().save(*args, **kwargs)
class Meta:
verbose_name_plural ='tool'

if field_value:
filtering_kwargs[field] = field_value
return filtering_kwargs
def get_queryset(self):
queryset = Tool.objects.all()
filtering_kwargs = self.get_kwargs_for_filtering() # get the fields with values for filtering
if filtering_kwargs:
queryset = Tool.objects.filter(**filtering_kwargs) # filter the queryset based on 'filtering_kwargs'
return queryset
from .models import Tool
from django.shortcuts import render
def index_view(request):
questions=None
if request.GET.get('crop'):
crop = request.GET.get('crop')
questions = Tool.objects.filter(crop__icontains=crop)
district = request.GET.get('district')
query = Tool.object.create(crop=crop, district=district)
query.save()
return render(request, 'index.html',{
'questions': questions,
})
what I have to change in views.py file for index.html to get parameter and gives exact information after user click on submit button ?
index.html
<form method="GET">
Crop: <input type="text" name="crop"><br/>
Taluka: <input type="text" name="taluka"><br/>
<input type="submit" value="Submit" />
</form><br/><br/>
{% for question in questions %}
<p>{{question}}</p>
{% endfor %}
can you help me how to get data and run the query ?
where I need to changes ?

Answer 1

Its a TYPO error in this line :
query = Tool.object.create(crop=crop, district=district)
object should be objects ,like this :
query = Tool.objects.create(crop=crop, district=district)
Update your code like this :
from .models import Tool
from django.shortcuts import render
def index_view(request):
questions=None
if request.GET.get('crop'):
crop = request.GET.get('crop')
questions = Tool.objects.filter(crop__icontains=crop)
district = request.GET.get('district')
query = Tool.objects.create(crop=crop, district=district)
query.save()
return render(request, 'index.html',{
'questions': questions,
})
And, Update the save method of your Tool model like this :
class Tool(Document):
crop = fields.StringField(required=True)
district = fields.StringField(required=True)
def __str__(self):
return self.crop
def save(self,*args, **kwargs):
super(Tool, self).save(*args, **kwargs)

Answer 2

In your index.html file, change {{question}} to {{question.crop}}. You have to refer to the field (in your case crop) on the model you want to render on your page.
Also, the default manager is located at Tool.objects not Tool.object.
In your models.py, super should be super(Tool, self). Also model Tool should inherit from django.db.models.Model. Your fields must be from django.db.models
class Tool(Model):
crop = models.CharField()
