[oba stephen]

The Error is straight forward, you are using an operand "+" for two two
data types that it can't be used on. This might be from your "volume"
function.

Re: Can someone help me??

[Sencer Hamarat]

File "D:\pythonwork\blog\personBlog\blog\views\index.py", line 25, in get
return render(request,'index.html',locals())

According to this line in that error seems to have occurred while rendering.
There is at least one "+" operation in "index.html" or "local()" method
call.
You have to check data types where the "+" operator used.
And also according to the error itself, the one of that value is not a
string.
I think the "ModelBase" model has no '__str__'.

Saygılarımla,
Sencer HAMARAT

Materializecss issue with CKeditor dialog

[Sherif Adigun]

If using materializecss for the application and image upload widget in the 
ckeditor, materializecss affects the dialog inputs making it impossible to 
use radio buttons and checkboxes. Do you have a suggestions on how to solve 
this?
I'm thinking of not loading the materialize css for the dialog box but i 
don't know how to make that work because i need to load that css file for 
the base page.

Please help

Re: How to display a line graph in Django?

[Yamen Gamal Eldin]

There's plotting library in Django.
But if I were u, I would send the data needs plotting to the template, and
plot it using a JavaScript library like chart js for small plots or d3 J's
for more professional ones.

Admin documentation incorrect hyperlinks

[Martyn Pearson]

I have an issue with Django, so wanted to raise it here before going to the 
extent of raising a bug.

For a simple scenario, I have a site "Survey", an app "Report" and models 
"Question" and "Answer". Note that the case is important; I've capitalised 
the first letter of each.

Admin documentation is turned on, and if I go to the documentation models 
page (e.g. http://localhost:8000/admin/doc/models/) I can see a link to the 
Question and Answer pages and this link takes me to the model pages 
correctly, for example the Question page at 
http://localhost:8000/admin/doc/models/Report.question/

However, if I try to follow any of the links on that page to other models - 
either those generated automatically or those I add through the use of the 
text :model:`Report.Question` they fail. It appears that the links have 
been generated using a lower case representation of the app, i.e. 
http://localhost:8000/admin/doc/models/report.question/ 
 rather than the 
correct case.

Does this indicate I have missed something or is this likely to be a bug 
which I need to raise on the bug tracker?

For transparency, I will add that I have posted this on Stack Overflow too 
- 
https://stackoverflow.com/questions/62656784/django-admin-documentation-with-mixed-case-project-name
 - 
but should either approach yield a solution I'll update the other for 
others reference.

Many thanks!

You bet - - - Zoom is a great choice if you like feeding the internet
information
slurp system. If you don't there are other systems out there. Have heard
suggestions of OpenMeeting and Jitsi but have only participated with
OpenMeeting and it seemed to work well most of the time.

Re: How to add domain from GoDaddy to Heroku

[Micah Beckman]

I finally got it sorted out. Buried deep in the blogs and FAQs they say that 
GoDaddy is going to be a problem, yet I have seen tutorials that use GoDaddy. 
Anyway, I got a domain on DNSimple and everything worked out immediately. They 
have a one-click connection to Heroku. Thank you for responding.

Primary keys using sequences

[Stats Student]

Hi, I am using a Postgres database and have been populating the primary key 
from a sequence. Is there any way to define this behavior through Django's 
ORM? Thanks.

I think you are basically asking how to create a custom key. This was  
discussed a few days ago, look for the thread "Custom Primary Key".

[oba stephen]

Can you share your models.py?

Like Sencer said you have to check data types where the "+" operator is
used.

 According to this line in that error seems to have occurred while
 rendering.
 There is at least one "+" operation in "index.html" or "local()" method
 call.
 You have to check data types where the "+" operator used.
 And also according to the error itself, the one of that value is not a
 string.
 I think the "ModelBase" model has no '__str__'.

Re: Can someone help me??

[Mohammed Alnajdi]

The error seems to be somewhere in the Urls

I think it might be issue with
"{% url 'blog:index/' %}"

try to remove the slash
"{% url 'blog:index' %}"

you might need to do the same with other urls

Thank you Oba Stephen and Mohammed Alnajdi.
I think this is a real BUG.
I'm ready to rebuild the project.
Thank you again.

 Like Sencer said you have to check data types where the "+" operator is
 used.
