Reducing size of columns in Flask-Admin

Question

Is there a way to limit the size (length/width) of a ModelView column? I am using a WYSIWYG editor and this creates really long text, therefor making the column for the ModelView very long.

Here is picture of what it looks like. Look on the right hand side the last column. It is even longer than the screenshot could handle.

Answer 1

Don't show the column (by exclusion):

class MyView(ModelView):

    column_exclude_list = ('description')

Don't show the column (by inclusion):

class MyView(ModelView):

    column_list = ('rating', 'category_id', 'year', 'stock', 'image')   

Reformat the column:

class MyView(ModelView):

     def _description_formatter(view, context, model, name):
        # Format your string here e.g show first 20 characters
        # can return any valid HTML e.g. a link to another view to show the detail or a popup window
        return model.description[:20]

    column_formatters = {
        'description': _description_formatter,
    }
