I am trying to create an application conference for which code files are below.
I am running into an error as can be seen from attached file when I click create conference button in conference_list.html file.

Error shown in Console:

I have included static files in base.html and extended in all other app_name_base.html files.

Culprit line as pointed by chrome browser is in file views.py of conferences app as follows:

return render(request , 'conferences/conference_create.html')

Please help. Files are shown below:

Edit and Solution:
I have also added modified conference_create.html file [Culprit line was line 9 as i needed to add action="% url 'conferences:create' %" in html form.
