sean@16: How to write a web-view module?
sean@16: ---
sean@16: 
sean@16: declare a specific tile in the dash.conf. for example:
sean@16: 
sean@16: ---
sean@16: [tile5]
sean@16: type=d3js
sean@16: div_name=webview_test
sean@16: script=webview_template
sean@16: ---
sean@16: (this will work for this file, see dash.conf for details)
sean@16: 
sean@16: bottledash will look for a "get_chart(target_div_name)"-methode wich shall
sean@16: return valid HTML-code (as string!).
sean@16: 
sean@16: the "target_div_name" is the "div_name" you delared in the dash.conf-file.
sean@16: In our case, "tile5" would be in the css-class "webview_test". You can use
sean@16: the "target_div_name" for dynamic DOM-Manipulations (like with d3js and jQuery)
sean@16: 
sean@16: If you want to use a python import, please use "importlib" inside the
sean@16: get_chart-function.
sean@16: 
sean@16: see <https://docs.python.org/3/library/importlib.html> for details
sean@16: 
sean@16: To not try to import your own modules using the regular
sean@16: python import-keyword! You can however import every regular
sean@16: python-standard-library using the "import" keyword
sean@16: 
sean@16: """
sean@16: 
sean@16: import importlib
sean@16: 
sean@16: def get_chart(target_div_name):
sean@16:     html_string = """
sean@16: <style type = text/css>
sean@16: 
sean@16: .%s {
sean@16:     color: red;
sean@16: }
sean@16: 
sean@16: </style>
sean@16: 
sean@16: <div id = "hello">
sean@16:     Hello World!
sean@16: </div>
sean@16:     """ % target_div_name
sean@16:
