Displaying lists with restricted number of products with Jquery

[anonymouscodar]

I am using jquery to present a number of products as per user's selection 
on "Show" dropdown menu. If user selects to get 9, 12, 16 or 20 products 
per page it should show accordingly in my list view.

Following is the code for HTML:


Show:

   9
   12
   24
   36
   48
   60
   90
   100



My list view varibale is:

items = Items.objects.all().

How can I restrict to load products according to the user's selected number 
of products?
Please help.

Regards,
A

Re: Displaying lists with restricted number of products with Jquery

[ludovic coues]

Slicing a list like you are trying to do is calling a pagination.
Django have a few tools for dealing with this problem. Here is a link
to the documentation:
https://docs.djangoproject.com/en/1.11/topics/pagination/

If you have any trouble using it, don't hesitate to ask for more details :)

Re: method's name in MIDDLEWARE

[m712 - Developer]

You should take a look at https://docs.djangoproject.com/en/1.11/topics/http/middleware/#process-view
It is not a reserved keyword but simply a function that is called by the Django middleware system.

Re: Dynamic Selector with Django/Jquery

[m712 - Developer]

You can create a URL in your application to which your AJAX code will send the details and the amount of items it wants and your application will return the items in JSON format. Take a look at https://docs.djangoproject.com/en/1.11/topics/db/queries/ to learn about how to filter and limit your queries to your need.

Bootstrap Tabs not working with Forloop rendered content

[Richard Jackson]

Hi everyone,

Having a Bootstrap/jQuery with Django issue so hope that someone might be 
able to help.

I'm rendering a part of my page to make a Bootstrap 'tab' (docs: link here 
) - however the 
content under the first heading isn't loading initially (img 1); it only 
renders when I select another heading then going back to it (img 2).



*Img 1: Initial page loading*




*Img 2: Going back to 'Singing' after selecting a different tab.*


Any thoughts on this? The code works just fine when I hard code it, it's 
just when the page is being rendered via forloops that the issue occurs.



 {% for p in page.tuitionpage.tuitioncontent.all %}
 
 {{ p }}
 
 {% endfor %}






 {% for p in page.tuitionpage.tuitioncontent.all %}
 
 {{ p.content|richtext_filters|safe }}
 
 {% endfor %}




  $(function () {
$('#myTab a:first').tab('show');
  })


Bootstrap v2.3.0
Django v1.8

Cheers!

Rich

Show HTML tags in list in Django template

[Moreplavec]

Greetings,

i'm trying to parse HTML website and present same basic info about it. I'm 
using BeuatifulSoup4 and Python3. Code is simple, but i have problem to 
force Django template show variables in my list. For example this simple 
code in template:

{{ tags_hx }}
> Tags H1 - H7
> 
> {% for tag in tags_hx %}
> 
> {% autoescape off %}{{ tag|safe }}{% endautoescape 
> %}
> 
> {% endfor %}
> 


 while {{ tags_hx }} prints lists exactly i have:

[Beginners English Tests 1, Grammar, 
> Beginners ESL, For Kids, Reading Skills, 
> Major Exams, Writing & Vocab]


but i can't get or force Django template to show each tag in table. All i 
get is:

Tags H1 - H7
> [Beginners English Tests 1]
> []
> []
> []
> []
> []
> [] 


I know, when i insert html code in template it will be used by browser, but 
just makes me mad i can't get to work it :) Autoescape or |safe doesn't 
help. Please, can you help me how to force simple output tags in cycle 
regardless of the consequences?

Thanks!

Re: Permissions in views

[Camilo Torres]

Hi,
Confirmed with Django 1.11, Python 3.4.3.
I strongly think this is a case you can report in bug tracker. Please tell 
if you will do.
I have been trying to find some time to test this since I read your message.

Re: getting error "Project matching query does not exist."

[Camilo Torres]

Hi,
I agree with Ludovic in "your application may be badly installed". But it 
is very hard to tell what is going wrong without actually knowing what your 
app should show (what view function) for URL path /brickly/home
I cannot tell you what view is that without knowing about your code nor 
your business rules for that page.
You have to ask the original developers what view should show there, and 
try to writhe the url conf for that.

Re: Activating VirtualEnv on Windows

[Camilo Torres]

Hi.
Try to run the .bat. May be it is a documentation error?

Re: Automatic reverse migrations

[Camilo Torres]

Hi,
May both of you try to implement "blue-green deployments", and switch only 
if all tests are OK.
You may also be interested in running a test deployment in a testing 
environment prior to production.
Don't know of a solution integrated into django.
