flask-admin

问题 I am using a model view with flask-admin and I want to filter a column in the edit/create view. The column/field is a relationship and I only want to show fields that belong to the logged in user i.e. relationship_id == user.id 回答1: Actually I found a easier way for that as below, seems there's no need to override the edit_form method in ModelView, just pass the filtering function as a named parameter(query_factory) to the form_args, and it works like a charming!. class CustomModelView

问题 I have a flask project, and I am getting started learning the flask-admin module. SqlAlchemy schema for the required tables. import datetime import sqlalchemy from sqlalchemy.ext.declarative import declarative_base from sqlalchemy.orm import backref, relationship Base = declarative_base() class Workgroup(Base): __tablename__ = 'workgroups' id = sqlalchemy.Column(sqlalchemy.Integer, primary_key=True, autoincrement=True ) name = sqlalchemy.Column(sqlalchemy.String(16)) shorthand = sqlalchemy

问题 I am using Flask-Admin for my Flask-based project. In it, I have some models (using peewee) where the primary-key is user-set, such as username for a User . However Flask-Admin is not showing these fields in the model's create/edit pages. Now, when I try to create a new user, the "Save" button gives a peewee.UserDoesNotExist error, and the "Save & Add" says "Record successfully created" twice but doesn't actually do anything. I had extended the save() method to auto-generate the username from

问题 I'm using Flask-Admin and I want to be able to update many fields at once from the list view. It seemed like what I'm looking for is a custom action. I was able to make it work, but I suspect not in the best way. I'm wondering if it could be done more "Flask"-ily. What I do now, for example if I was updating all rows in table cars to have tires = 4 : A custom action in the CarView class collects the ids of the rows to be modified, a callback url from request.referrer , and the tablename cars

问题 I have a User model class and password is one attribute among many. I am using Flask web framework and Flask-Admin extension to create the admin view of my model classes.

问题 When using flask-admin, the list view for datetime fields is something like this: "2014-02-22 13:30:43". I'd like to know if is possible to change this default view for something like this: "2014-02-22" or "2014-02-22 13:30". thanks 回答1: Yes, you can set the column_type_formatters to define default formats. Also, you can set column_formatters to use custom formats only to one column in your list view. https://flask-admin.readthedocs.org/en/latest/api/mod_model/#flask.ext.admin.model

问题 In my flask-admin index_view, I am displaying financial information for my rows. I would like to add an extra row, "summary row", at the bottom of my index_view table which sums up all the columns. How can I accomplish this? 回答1: There's a couple of things you need to do.
