Issue #78 resolved

Autogenerate does not detect decorated column type correctly

Robert Buchholz avatarRobert Buchholz created an issue

As per the SA example at http://docs.sqlalchemy.org/en/rel_0_7/orm/extensions/mutable.html#establishing-mutability-on-scalar-column-values

I have defined the TypeDecorator and used it as

parameters = Column(JSONEncodedDict(4096))

The auto-generated migration contains:

op.add_column('table', sa.Column('parameters', sa.JSONEncodedDict(), nullable=True))

When it should be

op.add_column('table', sa.Column('parameters', sa.VARCHAR(length=4096), nullable=True))

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
