Configuration#

Extracting reports from a source can be a challenging task and Dynamic Charts module aims to solve this task in an easy way. In order to activate the reports extraction, the model needs to be added in settings.

The section is a list of rules saved in a dictionary where the key is the path where the Dynamic Chart feature is provided and the value is the import path of the model.

core/settings.py#
# Syntax: URI -> Import_PATH
DYNAMIC_CHARTS = {
    "product": "home.models.Product",
    "sales": "home.models.Sales",
}

How it works#

The information is extracted and later showcased using a chart template where the user can edit a few properties like:

  • Chart Type: almost every popular type is supported: LINE, BAR, DONUT, RADAR .. etc

  • X-Axis column

  • Y-Axis column

  • Other column requsted by that speficic chart type

  • Each property can be preprocessed via filter like date-processor, uppercase .. etc

In the end, the chart template is applied on the model data and the charts displayed to the users using real data.

UI Sections#

All models registered in “settings.DYNAMIC_CHARTS” are shown in the home page of charts section:

When a model is selected, we can see all defined templates and also we can inspect the information on page or the embedded format, that can be integrated in external services.

  • Top section exposes three TABS

    • DataTable for data saved in the model

    • Add Item can be used to add a new item on the model

    • Add Chart: define a new chart

  • 2nd Section

    • Table with all the charts defined for the current model

  • Chart Section (bottom)

    • This section becomes visible when the user clicks the view link for a specific chart. For instance this is shown for a POLAR chart
