ValueError in models.py

Question

Here is my models.py file. When I try to migrate it gives me an error.

I changed Class name and it gives me an error. Now if I put even old name, it gives me the same error

from django.db import models
from tinymce.models import HTMLField



class BlockTags(models.Model):
    pass

class BlockTags_Text(models.Model):
    text = models.CharField(max_length=300, verbose_name='Заголовок 1', null=True, blank=True)
    block = models.ForeignKey(BlockTags, related_name="text", verbose_name='Заголовок 1', on_delete=models.CASCADE, null=True,blank=True)
    number = models.DecimalField(max_digits=3, decimal_places=0)







ValueError: The field content.BlockTags.text was declared with a lazy reference to 'content.blocktags_text', but app 'content' doesn't provide model 'blocktags_text'.

app 'content' doesn't provide model 'blocktags_text'.

This means that django doesnt see a blocktags_text model in your models.py, try running makemigrations and then migrate, also try adding at least one field to your empty model.

same thing, for makemigrations this error

The field content.BlockTags.text was declared with a lazy reference to 'content.blocktags_text', but app 'content' doesn't provide model 'blocktags_text'.

for migrate this ValueError: Related model 'content.blocktags_text' cannot be resolved
