django project: isort ignores local .cfg file's "skip" parameter

Django doesn't find some static files
I'm working on a project and since some days, one specific image cannot be found anymore. Everytime I reload the page, this line in the console appears: "GET /staticfiles/my_app/images/Logo.svg HTTP/1.1" 404 5715 I know that the image exists because sometimes it appears for a short moment (until you reload again) and other images in the same folder as the Logo.svg are also loading so I guess that the path is not the problem. The setting for the STATICFILES_DIRS is also correct since other things do work. STATICFILES_DIRS = ( os.path.join('my_app/static'), ) Did anyone have a problem like this before? -

How to use native sql elegantly in django?
In django, sometimes I have to write some native sql, which looks long and ugly,such as: SELECT 'TT' P_TYPE, KEY_NAME NAME, KEY_VALUE_1 || ' ' || KEY_VALUE_2 || ' ' || KEY_VALUE_3 || ' ' || KEY_VALUE_4 || ' ' || KEY_VALUE_5 || ' ' || KEY_VALUE_6 || ' ' || KEY_VALUE_7 VALUE, ADD_DATE FROM MY_T1_TABLE UNION ALL SELECT 'TT' P_TYPE, KEY_NAME NAME, KEY_VALUE_1 || ' ' || KEY_VALUE_2 || ' ' || KEY_VALUE_3 || ' ' || KEY_VALUE_4 || ' ' || KEY_VALUE_5 || ' ' || KEY_VALUE_6 || ' ' || KEY_VALUE_7 VALUE, ADD_DATE FROM MY_T2_TABLE UNION ALL SELECT 'EE' P_TYPE, NAME, VALUE, ADD_DATE FROM MY_E1_TABLE UNION ALL SELECT 'EE' P_TYPE, NAME, VALUE, ADD_DATE FROM MY_E2_TABLE I hope there is a way to integrate all the native sql in my code to make the code look more beautiful.I have tried putting all the sql into a py file, using variables to define and call the sql, I don't know if this is a good solution, or who has a better solution? -
Hiding extra field Django Admin
I want to display an extra field based on a boolean check associated with the model. if obj.boolean: exclude(self.extra_field) But the issue with this is that the extra field is not associated with the model so it is throwing error stating model does not contain this extra field. The output that i am looking for is that, when this boolean is true the extra field should not get displayed in the model admin as well as model inline. But when it is false it should get displayed. How can i achieve this? -
It is impossible to add a non-nullable field 'name' to table_name without specifying a default
I have added a following field in my already existing model: name = models.CharField(max_length=128, unique=True) But it is giving following prompt when applying migrations: It is impossible to add a non-nullable field 'name' to table_name without specifying a default. This is because 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 manually define a default value in models.py. I cannot set it's attributes to blank=True, null=True as this field is must. I cannot set it's default value as the field has to be unique. If I try to set it's default value in command prompt, it says plz select a valid option. How to fix it? -
