In your custom ModelView, you need to add the following lines: from flask.ext.admin.model.template import macro column_formatters = dict(your_column=macro('render_your_column')) list_template = 'list.html'
In your custom list.html template, you need to add the following jinja2 code: {% macro render_your_column(model, column) %} {% if model.your_column%}<i class="icon-ok"></i>{% endif %} {% endmacro %}
If your row has a value in "your_column", then it will show as a checkmark. You need to make a new macro for each column.
Flask-Migrate is exactly what I've been looking for when it comes to database migrations. When I create PHP applications with MVC frameworks, the changes in the database need to be done manually when the model is changed. Flask-Migrate handles changes to the database (like adding/removing columns) so your models reflect your database.
This is a big advantage Flask has over PHP frameworks.
If you have strawberry perl installed, you may get one of these errors when you try to use pip from powershell:
Did not provide a command
Unknown or unsupported command 'install'
This is the result of a conflict between strawberry perl's pip and python's pip. You need to remove anything related to strawberry perl from your path environmental variable and ensure you have C:\Python27\Scripts and C:\Python27\Scripts in your environmental variables.
I was planning to use "Trusted Authentication" to share an embedded chart with lots of users (not all of whom have licenses). Some of those users will only look at the chart maybe once a year, and we can't justify buying them an entire license to look at a chart once.
If you want more details on how to implement Trusted Authentication using PHP, first visit the following folder on your server: C:\Program Files\Tableau\Tableau Server\8.1\extras\embedding\php
It has some sample code, but you need to install version 1.x of pecl_http to make it work. The guides for that are:
Basically, your web application isn't thread-safe if you're not using scoped_session. It's much better than having you application use a new thread for every instance.
Just putting index.html into an admin/ directory wouldn't work.
There's also an even shorter way to do it, for example: admin = Admin(app, "G-Cal Manager", index_view=AdminIndexView(name='Home', template='admin/home.html', url='/'))
The example above will change the root url to / instead of /admin and it will use home.html from your templates/admin folder.
To fix the 404 errors on your stylesheets after the change, you will also need to change the static_folder in your flask object: app = Flask(__name__, static_folder='admin')
