Trying to use tooltips in django 2.0 form

[Alan]

Hi there,

I have this in my forms.py:

class SubmissionForm(forms.Form):


molecule_file =
forms.FileField(validators=[FileExtensionValidator(settings.CONTENT_TYPES),
file_size], help_text="Required: Select a PDB, MDL or MOL2 file")

But I am failing to make it work in my submit.html template. Currently, I
am "hacking" with:


{{form.molecule_file.label}}{{ form.molecule_file }}

That will show the tooltip "Required: Sel..." if mouse pause over this
field in the browser, but this is silly, I wish I could use something like:


{{form.molecule_file.label}}{{ form.molecule_file }}

But that is not working, neither any combination I tried with .title etc.

Any suggestion would be very much appreciated.

Many thanks in advance,

Alan

Hii Indrajeet,
You can use virtual environment which would help you to 
separate your project from the rest of the project working on your computer 
and is highly recommended.
 make a directory on your desktop(mkdir {name of the 
folder})
 cd (name of the folder)
 virtualenv .  (creates a virtual enviroment)
 source bin/activate (activates the virtualenv)
 pip install django (downloads the latest version of 
django)
 pip install django==(specific version if you want to 
download)
 ls(shows one manage.py file)
 python manage.py runserver generates your first django 
powered page.

Disconnect WS on server shutdown

[Igor Partola]

I am running into an issue with one of my applications that is running on 
Heroku. Basically during a deploy, the old daphne process gets shut down 
and a new one takes over. The problem with this is that some users are 
still connected to the old daphne process and are still members of various 
groups that get notifications via WS. This is problematic because it seems 
that the daphne server being shutdown does not right away get detected by 
the browsers.

Is there a way to close the WS connections from daphne when it receives the 
TERM signal?

Seeking professional help for frontend design for a small django project

[cjwalter]

Hi everybody

I’ve started a small django website which is up and running but could 
benefit from some frontend polish (bootstrap3). As I need to launch it by 
end of this week this is kind of time critical, but I assume for someone 
who is specializing in this kind of work it will take a few hours only. 

We shall communicate via skype with screen sharing and you will get a full 
copy of the django project including a database dump to load it at your 
site. Please contact me via eMail (cjwalt...@gmail.com)

Best regards

cj

Alan,

The use of "help_text" in a template is shown here:
https://docs.djangoproject.com/en/2.0/topics/forms/#looping-over-the-form-s-fields

That is an example of how you should render a form field "manually". You
may also try seeing the output of {{ form.as_p }} and then tweak it to your
needs (you can use that in whatever tooltip wrapper - like bootstrap or
other css frameworks).

HTH!

Not to my knowledge.
Here is an example of metric processing in Django:

The whole process is described there, it can tweak it to your needs
