In forms.py I have created a formset using formset_factory with extra=6
class Associe(forms.Form):
nom= forms.CharField(max_length=40)
AssocieFormSet=formset_factory(Associe,extra=6)
in my page.html I wrote a loop to write my forms 6 times, but I nead the number in the id, I know Django will give form-0-nom for the first element, and id_form-1-nom for the seconde element and so on, and I know how to get the whole id of the element.
But how can I get only the number of each element's id?
I think an easy way of getting the form number would be by using the template tags forloop.counter0 or forloop.counter. So with forloop.counter0, form-0-nom will have the number 0 within that iteration and you can do what you want with that number.

I am working on a test that checks that all images on a page are visible. I'm running into an issue where its only pulling the link from the first img on the page and logs it the length of the loop. Im currently getting a count of all the images, and in that count I loop through and pull the img source. There are no special classes, or ids. The only thing I have to go off of is . I'm guessing I will somehow need to parse the entire HTML since robotframework only looks at what is viewable on the screen?
My end goal is to pull all img sources on a page and confirm each one returns a 200 status code.
Here is what I have now:
#{all_image_sources} Create List
${all_images} Get Element Count //body//img
FOR ${image} IN RANGE ${all_images}
${img_src} Get Element Attribute tag:img src
log ${img_src}
Append To List ${all_image_sources} ${img_src}
END
Log List ${all_image_sources}'''
You might consider using Get WebElements, this will give you each image locator in a list. You can then loop through the list to get each src attribute.
example:
#{all_image_sources} Create List
${all_images} Get WebElements //body//img
FOR ${image} IN #{all_images}
${img_src} Get Element Attribute ${image} src
Append To List ${all_image_sources} ${img_src}
END
Log List ${all_image_sources}

I'm trying to scrape text from a website, but specifically only the text that's linked to with one of two specific links, and then additionally scrape another text string that follows shortly after it.
The second text string is easy to scrape because it includes a unique class I can target, so I've already gotten that working, but I haven't been able to successfully scrape the first text (with the one of two specific links).
I found this SO question ( Find specific link w/ beautifulsoup ) and tried to implement variations of that, but wasn't able to get it to work.
Here's a snippet of the HTML code I'm trying to scrape. This patter recurs repeatedly over the course of each page I'm scraping:
<em>[女孩]</em> 寻找2003年出生2004年失踪贵州省黔西南布依族苗族自治州贞丰县珉谷镇锅底冲 黄冬冬289179
The two parts I'm trying to scrape and then store together in a list are the two Chinese-language text strings.
The first of these, 女孩, which means female, is the one I haven't been able to scrape successfully.
This is always preceded by one of these two links:
forum.php?mod=forumdisplay&fid=191&filter=typeid&typeid=19 (Female)
forum.php?mod=forumdisplay&fid=191&filter=typeid&typeid=15 (Male)
I've tested a whole bunch of different things, including things like:
gender_containers = soup.find_all('a', href = 'forum.php?mod=forumdisplay&fid=191&filter=typeid&typeid=19')
print(gender_containers.get_text())
But for everything I've tried, I keep getting errors like:
ResultSet object has no attribute 'get_text'. You're probably treating a list of items like a single item. Did you call find_all() when you meant to call find()?
I think that I'm not successfully finding those links to grab the text, but my rudimentary Python skills thus far have failed me in figuring out how to make it happen.
What I want to have happen ultimately is to scrape each page such that the two strings in this code (女孩 and 寻找2003年出生2004年失踪贵州省...)
<em>[女孩]</em> 寻找2003年出生2004年失踪贵州省黔西南布依族苗族自治州贞丰县珉谷镇锅底冲 黄冬冬289179
...are scraped as two separate variables so that I can store them as two items in a list and then iterate down to the next instance of this code, scrape those two text snippets and store them as another list, etc. I'm building a list of list in which I want each row/nested list to contain two strings: the gender (女孩 or 男孩）and then the longer string, which has a lot more variation.
(But currently I have working code that scrapes and stores that, I just haven't been able to get the gender part to work.)
Sounds like you could use attribute = value css selector with $ ends with operator
If there can only be one occurrence per page
soup.select_one("[href$='typeid=19'], [href$='typeid=15']").text
This is assuming those typeid=19 or typeid=15 only occur at the end of the strings of interest. The "," between the two in the selector is to allow for matching on either.
You could additionally handle possibility of not being present as follows:
from bs4 import BeautifulSoup
html ='''<em>[女孩]</em> 寻找2003年出生2004年失踪贵州省黔西南布依族苗族自治州贞丰县珉谷镇锅底冲 黄冬冬289179'''
soup=BeautifulSoup(html,'html.parser')
gender = soup.select_one("[href$='typeid=19'], [href$='typeid=15']").text if soup.select_one("[href$='typeid=19'], [href$='typeid=15']") is not None else 'Not found'
print(gender)
Multiple values:
genders = [item.text for item in soup.select_one("[href$='typeid=19'], [href$='typeid=15']")]
Try the following code.
from bs4 import BeautifulSoup
data='''<em>[女孩]</em> 寻找2003年出生2004年失踪贵州省黔西南布依族苗族自治州贞丰县珉谷镇锅底冲 黄冬冬289179'''
soup=BeautifulSoup(data,'html.parser')
print(soup.select_one('em').text)
OutPut:
[女孩]
Alright, so I'm pretty new to Spring, but I was asked to resolve a bug. So in our application, we have a page that queries a database based on an id. However, not all entries are unique to the id. The id and date pair, on the other hand, do define unique entries.
So this page takes in an id. If there is only a single entry related to this id, everything works fine. However, if there are multiple entries, the page displays a radio button selection of the various dates that pertain to that id. We use something like:
< form:radiobutton id="loadDate" path="loadDate" value="${date}" label="${date}" />
Later on the same page, we want to display the data for that option. As part of it, we display the date of that selection:
< form:input id="aiLoadDate" path="loadDate" maxlength="22" size="22" class="readonly" readonly="true"/>
The problem is that when this happens, the variable (or bean? I'm not quite sure about Spring yet..) loadDate (a string) ends up being the same date twice, seperated with a comma. I'm guessing the problem here is the "path="loadDate"" that is common to both lines.
Instead of appending the date to the already existing one like a csv, I'd like it to overwrite the current entry intead. Is there a way to do this?
Spring is not the direct cause of your problem. When the elements of an HTML form are submitted, each element will appear in the request as a name=value pair. If two or more elements in the form have the same name (not id, name attribute) then those elements appear in the request as name=value,value (with one value per element with a duplicated name).
Option 1: stop using an input as a display element. Just display the date in a span (or div or paragraph or what ever). If you want the look of an input box (border, etc.) use CSS to create a class that has the look you want and attach the class to the span (or div or paragraph, etc) in which you display the date.
Option2: continue using an input as a display element. Disabled input elements are not added to the request when the form is submitted. in the form:imput set disabled="true".
Im having a hard time deciding what is the best way to pull pictures from a separate table, for a certain item.
In django, I have two tables:
class item(models.Model):
title..
descr..
class item_pic(models.Model):
item=models.ForeignKey(item)
pic=models.ImageField...
Im displaying the item.title and item.descr in a div, and in the same div I want to pull the pictures.
So far I've tried creating a template filter like item|getPics which returns a list of the pics for that item.
{% for pic in item|getPics %} <img src="/uploads/{{pic.pic}}"> {%endfor%}
In the end I got rid of this since it was firing too many sql queries
Right now I finished pulling the pictures through ajax, the only downside here is that the images take some time to appear. And I assume is the same number of sql queries (only that django debug toolbar doesnt see them since they are fired up in the background).
How would you approach this? Thanks for any tips!
You should use select_related() (docs) to get the image objects together with the items.
It would look like this:
item = item.objects.select_related().get(...)
This means you won't get additional database queries when you're retrieving the item_pics.
As a final note, it's better to capitalize the names of classes as this is convention in Python/Django.
In my application i want to keep my Form id in the Dom element So that on click of my Dom element, i get to know the Form id and make use of that for further purpose.
For eg:
my app has a list of form names generated like
Contact Form
Personal Form
I want to save my form id that is 1 somewhere in the Dom element a.
And onclick of that link i want to make use of it for further things . How can i do .. Where can i save my Form id in the Dom element.Please suggest me..
Edit:
In my application by using JQuery, i am generating list of Form names by fetching it from by MYSQL database using CakePHP framework.
eg:
$('#entryManager').click(function(){
$("<p class='title2'>Forms</p>").appendTo("#fb_contentarea_col1top");
$("<ul class='formfield'>").appendTo("#fb_contentarea_col1down");
<?php foreach ($Forms as $r): ?>
$("<li><a id=Form'<?=$r['Form']['id'];?>' href='/FormBuilder/index.php/main/entryManager'><?=$r['Form']['name']?></a></li>").appendTo("#fb_contentarea_col1down .formfield");
<?php endforeach; ?>
return false;
});//entry Manager Click
On click of Entry manager the Form names are listed .
And now i want to use some function like onclick of each Form name i want to retrieve the Entries filled by invitees from the database.For this i want the FOrm id each Form name to store it somewhere in the DOm element so that i can get that value (form id) and send it to my ajax request to fetch the entries filled..How can i do so???
Don't use purely numeric id's, it's best if they start with a letter, but essentially you can can have...
<form id="form1"...>
And then store the information in your anchor like this...
<a rel="form1">Click...
Then you can pull the "rel" tag out and use it to reference form1.
This is technically stretching the purpose of the rel tag, but does work.
document.forms is an array that contains all of your forms and you can do something like this:
document.forms['myFormId'] and you would get the form of that ID. But yet I am not getting what you are trying to achieve. May be if you elaborate on it further then I can guide you better on this.
