I don't know why,
in local
localhost:8000/sitemap.xml will generate sitemap.xml.

But on heroku,
domain/sitemap.xml will error h13.

I followed this tutorial
https://jawaban.online/scope/outlink/6442/django-sitemap-tutorial-help-crawlers-understand-your-website-2018-youtube/
and
https://medium.com/analytics-vidhya/django-sitemap-8f4ca0538fa

Any suggestions?
Thanks.

Re: I got this error "ValueError: attempted relative import beyond top-level package "

localhost:8000/sitemap.xml will generate sitemap.xml.

But on heroku,
domain/sitemap.xml will error h13.

Any suggestions?
Thanks.

 Not sure why you are importing this into your main project urls.py but
 its very straight forward

 from blog.sitemaps import BlogPostsSitemap

 question... are you trying to map the application url here? then you
 should use path('/' , Include("blog.urls"))

Re: AttributeError: object has no attribute 'user' while trying to access instance.user.id

I wanted to see your model to understand but i realized after my last post 
that you are using "instance.user.id" while your employee instance does not 
have user field. (had to go somewhere urgently) >>> return 
"employees/media/users/{0}/profile_picture.{1}".format(instance.user.id, 
extension)  

change it as follow and remove user from it.
return "employees/media/users/{0}/profile_picture.{1}".format(instance.id 
, extension)  

It should work...

Re: AttributeError: object has no attribute 'user' while trying to access instance.user.id

coolguy here is the complete Employee model:

class Employee(models.Model): #TODO: Double-check this
username = models.CharField(max_length=50, unique=True)
email = models.EmailField()
password = models.CharField(max_length=50)
first_name = models.CharField(max_length=150)

website = models.URLField(max_length=200, blank=True)
profile_picture = models.ImageField(upload_to=get_upload_path, 
blank=True, null=True)

def __str__(self):
return str(self.first_name) + str(self.last_name)

*Why do I need the foreign key to User in the first place?* I don't recall

Re: I am getting an error message about a non-nullable field in existing rows, even though I dropped all rows via the admin interface

coolguy:

I tried it without the quotes. Maybe that was the issue.

AttributeError: object has no attribute 'user' while trying to access instance.user.id

Hey guys,

I have the following code in models.py file in one of my apps:

def get_upload_path(instance, filename):
extension = filename.split('.')[-1]
return "employees/media/users/{0}/profile_picture.{1}".format(
instance.user.id, extension)

class Employee(models.Model):
# some attributes here
profile_picture = models.ImageField(upload_to=get_upload_path,
blank=True, null=True)

I am getting the following error when I try to add an Employee via the
admin interface:

AttributeError at /admin/employees/employee/add/

'Employee' object has no attribute 'user'

*I don't know where this error is stemming from.* I took the
get_upload_path function from the official Django FIleField documentation
.

Any ideas as to what is going on here?

Best,
Mislav

Re: I am getting an error message about a non-nullable field in existing rows, even though I dropped all rows via the admin interface

A question to coolguy:

*What should I have done if I selected option 1?* I get the Python shell 
and if I input a default value - let's say "t...@test.com", what else do I 
need to do? I tried to just provide the default value, but it wouldn't 
accept it, complaining that it was invalid Python (as it is). *Do I need to 
select the existing rows from the database and set them all to have the 
value of the new field to the default value? If yes, how do I do this most 
efficiently (in code)?*

Best,
Mislav

 Hey guys,

 I added an EmailField 

 to some of my already existing models. When I tried to run:

 *python manage.py makemigrations*

 I got the following prompt:

 *You are trying to add a non-nullable field 'email' to employee without 
 a default; we can't do that (the database needs something to populate 
 existing rows).Please select a fix: 1) Provide a one-off default now (will 
 be set on all existing rows with a null value for this column) 2) Quit, 
 and 
 let me add a default in models.pySelect an option: *

 I quit the prompt (option two). Then I went ahead and commented out the 
 new EmailField in the models I added them and I dropped all of the 
 database 
 rows in my entire database (not just the rows related to the models where 
 I 
 added the new email field; I dropped every row from every table).

 Then I uncommented the new EmailField and tried to run:

 *python manage.py makemigrations*

 again, *but I still get the prompt above*! I selected option 1 a few 
 times, but I'm not sure what I need to do. I tried to supply a value for 
 that field, but the prompt is a Python shell, so I'm not sure what I need 
 to do if I select option 1.

 *How do I fix this?*

 Best,
 Mislav

Re: Environment Variables for Django Secret Key etc On Windows 10 and Heroku

Yes, I've seen so many tutorials. I did the same thing, and didn't work.
I believe there is something wrong with my Django Project. I don't know
what it is.
Still tinkering.

Re: I am getting this error while I click on comment button which i mention in line 51 in html file.

Can't see the line number in your provided screens.
However, i can see you have additional id id={{ i.id }}added to your button 
line. (remove it)
You have already provided the id in href="{% url 'userpage:post_detail'

Re: I am getting an error message about a non-nullable field in existing rows, even though I dropped all rows via the admin interface

2020-09-12 Thread Mohammad Ahshan Danish

yes it works after deletion because old records get deleted.

but better approach is to do changes in migration.py files

Re: I am getting an error message about a non-nullable field in existing rows, even though I dropped all rows via the admin interface

just FYI...

You didn't have to delete the db.sqllite3 file rather would have followed 
on-screen direction and provided a default value to persist in the existing 
records in your database. Later you could have edited the info through your 
program and make correction.

This is pretty normal situation where we added new fields/properties in our 
model while database has existing records. You wouldn't be able to delete 
the database in case you are using relational database like postgres or 
mysql.

Thanks

Hi Odeyale,

I assume you must have an extremely slow internet connection. Try 
increasing the timeout to the pip command as documented here:


https://pip.pypa.io/en/stable/user_guide/

E.g:

# pip install --default-timeout=120 Django-3.1.1

Kind regards,

Kasper Laudrup

Re: I am getting an error message about a non-nullable field in existing rows, even though I dropped all rows via the admin interface

Hey Danish,

I was able to resolve the error by deleting the *db.sqlite3* file from my 
project root directory and all of the *migrations* folders from all of my 
apps.

Thank you for responding.

I am getting an error message about a non-nullable field in existing rows, even though I dropped all rows via the admin interface

Hey guys,

I added an EmailField
to
some of my already existing models. When I tried to run:

*python manage.py makemigrations*

I got the following prompt:

*You are trying to add a non-nullable field 'email' to employee without a
default; we can't do that (the database needs something to populate
existing rows).Please select a fix: 1) Provide a one-off default now (will
be set on all existing rows with a null value for this column) 2) Quit, and
let me add a default in models.pySelect an option: *

I quit the prompt (option two). Then I went ahead and commented out the new
EmailField in the models I added them and I dropped all of the database
rows in my entire database (not just the rows related to the models where I
added the new email field; I dropped every row from every table).

Then I uncommented the new EmailField and tried to run:

*python manage.py makemigrations*

again, *but I still get the prompt above*! I selected option 1 a few times,
but I'm not sure what I need to do. I tried to supply a value for that
field, but the prompt is a Python shell, so I'm not sure what I need to do
if I select option 1.

*How do I fix this?*

Best,
Mislav

Re: 404 error

2020-09-12 Thread Spyke Lionel

yes I did. it should work properly.
I just wanna display a list of items after the link has been clicked.
But it happens that I get http://127.0.0.1:8000/music//
The last forward slash shouldn't have added.
This work when the integer is inserted manually on the address.
http://127.0.0.1:8000/music/2/
But I want it to happen this way when a link is clicked
