python flask partically update webpage

I am trying to use python flask framework to build a webpage. This webpage is a dashboard, which has two divs. The first div is a table, each row of which is the info for a certain stock. The second div is a chart which shows the price curve for one of the stocks in the first table.

I would like to refresh the second chart based on the selection from the first table. For example, if I click on the name of stock A in the first table, the price curve for A is then showed in the second chart.

One way to implement this, is to link each stock name to a different url, and have a html file associated with each url address. A series of render_template functions have to be defined in the view.py script.

I wonder if there's a more generic way to implement this. Maybe one function definition and one html template would be enough for all stocks in the table?

thanks!

You can generate URL in flask using url_for(). So maybe your template to generate charts can use url_for('/stock', stock_name='GOOG'). Which will embed the route /stock/GOOG into a link to show a chart for GOOG.

Then you can use a nested template to show the chart div when the above route is called.

Here is link to the relevant documentation: http://flask.pocoo.org/docs/0.11/quickstart/#url-building http://flask.pocoo.org/docs/0.11/patterns/templateinheritance/
