Can you add html meta-description to django blog post model?
I'm wondering if it's possible/google allows to add a meta_description CharField to Post model to dynamically change meta description on html page? My current meta description is <meta name="description" content="{{ post.title }} blog post from the {{ post.category }} category."> Which obviously isn't ideal as it doesn't give a great description of the individual blog post. Then I got to thinking of whether I can just add a field to set in the same manor. This way I would be able to set the CharField to max length so I know all meta descriptions are proper length, and I would be able to set a proper description for each blog post. class Post(models.Model): title = models.CharField(max_length =250) body = RichTextField(blank=True, null=True) meta_description = models.CharField(max_length=150) <meta name="description" content="{{ post.meta_description }}" Does anyone see any issues with this before I attempt to implement it? Does anyone know if this is allowed by Google? Thanks in advance. I would have attempted this first to see if it would work but I'm still quite new, and last time I attempted to add a field to an existing model with existing objects I screwed it up and all existing objects would cause an error, so … -

How to limit the IO for postgres for a particular python script?
I have a server with nginx, gunicorn, django and postgres, which serves a website. In the background I need to have a script that is continuously consuming an external API and writing to the database. Currently I'm hitting the IO limit of my SSD (looking at nmon data) and as a result the website is very slow when the script is running. I read something about ionice that it can set an IO priority for a PID, but putting that on the python script doesn't help, because it's the postgres process that's doing the work. Is there a way to have a separate postgres process dedicated to that particular python script with limited IO? -

Django Allauth asking for password 3 times in signup page

Why is fetch always returning undefined here?
I am working on a Unit Conversion API, and I am having a lot of issues with fetch(). My backend API is working, for example, when I call curl "http://localhost:8000/unitconv/convert?to=lb&from=kg&value=10" I get the correct response: {"units": "lb", "value": 22.04623}. Yet when I do the exact same thing with fetch(), this is what I get: I have tried both localhost and 127.0.0.1 and I still cannot get past this "undefined". What's wrong here? -
model condition in admin panel
I created several tables in models.py and in these tables I have a table named "Asset" that I added assets. my Asset table features are name, description, point geometry and line geometry. For this table, when I enter the django admin panel and add assets with "+ Add", I want an option to appear first. A or B will be selected as an option. If I press A, let only name, description and point geometry come from properties of Asset table for asset record. If I press B, the name, description and line geometry come up. How do I do this conditional choice? -

FileField not populated after validation error
In my form I have several FileFields. If I provide a file with a wrong extension I get a Validation Error. When the form is reloaded the validation errors are shown.
