operationalerror - error de la base de datos no such table django

migrate no such table

Question

He hecho una nueva aplicación ''api'' en el proyecto django ''cc''.

Tengo una base de datos remota ''launchg'' que integé con Django usando Legacies y usé python manage.py inspectdb > models.py para generar un archivo models.py .

A continuación, reemplazó el archivo models.py generado con el archivo models.py en la aplicación api .

Cada vez que intento disparar una consulta en este database error:no such table datos de database error:no such table para Eg: - WebQuery.objects.all() , arroja un error que indica database error: no such table : web_query

Aquí está mi archivo models.py

    # This is an auto-generated Django model module.
    # You''ll have to do the following manually to clean this up:
    #     * Rearrange models'' order  
    #     * Make sure each model has one field with primary_key=True
    # Feel free to rename the models, but don''t rename db_table values or field names.
    #
    # Also note: You''ll have to insert the output of ''django-admin.py sqlcustom [appname]''
    # into your database.

Además, cuando manage.py sql api el comando manage.py sql api , muestra todas las tablas. ¿¿¿Qué es???

Amablemente ayuda!

Answer 1

La principal diferencia es que al manage.py sql myapphere se mostrarán las consultas utilizadas para crear el esquema para su base de datos, mientras que la myapp.objects.all() de myapp.objects.all() simplemente devolverá una lista de las entradas en esa base de datos.

Por ejemplo, si tiene una lista de artículos, el comando manage.py sql mostrará las propiedades de myapp mientras que myapp.objects.all () mostrará las instancias de myapp en la base de datos.

Para seguir extrapolando su problema, intente abrir su cliente de base de datos y asegúrese de que los nombres de columna coincidan con los descritos en su modelo. Si no coinciden, es posible que deba abandonar la tabla y resincronizar su base de datos (definitivamente tuve ese problema).
