Using ModelForm to get labels in a DetailView

[bnmng]

I don't know if this is good practice, but to get field labels in a 
DetailView, it seems to work fine if you just add a form to the context:

views.py:

class ItemDetailView(DetailView):

model = Item
context_object_name = "item"

def get_context_data(self, **kwargs):
context_data = super().get_context_data(**kwargs)
context_data['form'] = ItemForm # just to get the labels
return context_data


item_detail_view.html:

{{ form.name.label_tag }} {{ 
item.name }}
{{ form.notes.label_tag }} {{ 
item.notes }}
{{ form.asset_number.label_tag }} {{ item.asset_number }}
{{ form.serial_number.label_tag }} {{ item.serial_number }}
{{ form.network_name.label_tag }} {{ item.network_name }}

Re: Idea

[Helin Cao]

To answer your 2nd question: there is PyWebIO, an open-source library that
allows you to write web UI using only Python and deploy it as a Django app:
GitHub: https://github.com/pywebio/PyWebIO
Doc: https://pywebio.readthedocs.io/en/latest/

BTW, if you like other Python-based web frameworks, it also supports, such
as Flask, FastAPI etc.

Re: How to update old data with new data everyday from a scraper

[Adib Neymar Jr.]

Interesting, is there a way to peek for an existing record instead of 
calling get to see whether the record exists in the database? I'm thinking 
of making this snippet of code a bit more efficient

try:
   obj = Hackathon.objects.get(**each_dict)
except Hackathon.DoesNotExist:
   obj = Hackathon(**each_dict)
   obj.save()

Auto populating business organization logos

[Ram]

Hi,

As most of you know LinkedIn automatically adds a logo of a company when
you update your profile with work experience from that company. Similar to
that functionality, is there a  way to auto  populate any business
organizaiton logo in Django?  I guess this can be done using an API but not
sure who provides such API?

Any pointers will be appreciated.

Best regards,
~Ram

Re: Auto populating business organization logos

[Shishir Jha]

I believe linkedin is not using any api. Why would they need that? All the
companies have their own accounts in the linkedin itself right? Thats how
you apply to them. So linkedin muat be using images from its own database
and not from some third party api.

'str' object is not callable error appears from Django Message Framework

[Salima Begum]

Hi all,


Our web application prompts confirmation messages when user submits the
form and users can continue to submit additional forms while they are using
application and the confirmation messages are prompted fine, but  'str'
object is not callable error appears randomly before prompting a
confirmation message and once this error starts appearing it will continue
to appear for any form submission. During our testing we observed that this
issue is happening  in Django version 3.2.7 (ubuntu 20.x), but it is not
reproducible in Django version 3.1.6 (windows10). So, we think that this
could be a bug in version 3.2.7 . We made sure our code by following this
page.

https://docs.djangoproject.com/en/3.2/ref/contrib/messages/

In views.py :

{{{
 messages.success(request, "Item is successfully removed.")
}}}


In template:

{{{
 {% for message in messages %}


×
{% if message.tags == 'error' %}
   
{{ message|safe }}  
{% else %}
 
   {{ message|safe
}}  
{% endif %}


{% endfor %}
}}}
