Remodelar Journal, removendo os textos com idiomas para os modelos JournalPolicies e JournalInstructionsToAuthors

[Roberta Takenaka]

Descrição da tarefa

Estamos experimentando problemas de desempenho. Possível solução é reduzir o modelo Journal, removendo os textos com idiomas para outros modelos, JournalPolicies e JournalInstructionsToAuthors.

A nova modelagem pode ter a seleção de um idioma para um grupo de textos.

Por exemplo, no lugar de:

panels_policy = [
        InlinePanel(
            "ethics",
            label=_("Ethics"),
            classname="collapsed",
        ),
        InlinePanel(
            "ecommittee",
            label=_("Ethics Committee"),
            classname="collapsed",
        ),
        InlinePanel(
            "copyright",
            label=_("Copyright"),
            classname="collapsed",
        ),
]

class Ethics(ClusterableModel, RichTextWithLanguage, CommonControlField):
    journal = ParentalKey(
        Journal, on_delete=models.SET_NULL, related_name="ethics", null=True
    )

            """Authors must attach a statement of approval from the ethics committee of 
            the institution responsible for approving the research"""
        ),
    )
    journal = ParentalKey(
        Journal, on_delete=models.SET_NULL, related_name="ecommittee", null=True
    )

        ),
    )
    journal = ParentalKey(

    )
