Use Dash to Build to Web Apps on SuiteCRM Data

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData Python Connector for SuiteCRM, the pandas module, and the Dash framework, you can build SuiteCRM-connected web applications for SuiteCRM data. This article shows how to connect to SuiteCRM with the CData Connector and use pandas and Dash to build a simple web app for visualizing SuiteCRM data.

With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live SuiteCRM data in Python. When you issue complex SQL queries from SuiteCRM, the driver pushes supported SQL operations, like filters and aggregations, directly to SuiteCRM and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to SuiteCRM Data

Connecting to SuiteCRM data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.

The User and Password properties must be set to valid SuiteCRM user credentials. Additionally, specify the URL to the SuiteCRM application, for example http://suite.crm.com.

Note that retrieving SuiteCRM metadata can be expensive. It is advised that you store the metadata locally as described in the Caching Metadata section of the data provider help documentation.

After installing the CData SuiteCRM Connector, follow the procedure below to install the other required modules and start accessing SuiteCRM through Python objects.

Install Required Modules

Use the pip utility to install the required modules and frameworks:

pip install pandas
pip install dash
pip install dash-daq

Visualize SuiteCRM Data in Python

Once the required modules and frameworks are installed, we are ready to build our web app. Code snippets follow, but the full source code is available at the end of the article.

First, be sure to import the modules (including the CData Connector) with the following:

import os
import dash
import dash_core_components as dcc
import dash_html_components as html
import pandas as pd
import cdata.suitecrm as mod
import plotly.graph_objs as go

You can now connect with a connection string. Use the connect function for the CData SuiteCRM Connector to create a connection for working with SuiteCRM data.

cnxn = mod.connect("URL=http://mySuiteCRM.com;User=myUser;Password=myPassword;")

Execute SQL to SuiteCRM

Use the read_sql function from pandas to execute any SQL statement and store the result set in a DataFrame.

df = pd.read_sql("SELECT Name, Industry FROM Accounts WHERE Industry = 'Manufacturing'", cnxn)

Configure the Web App

With the query results stored in a DataFrame, we can begin configuring the web app, assigning a name, stylesheet, and title.

app_name = 'dash-suitecrmedataplot'

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.title = 'CData + Dash'

Configure the Layout

The next step is to create a bar graph based on our SuiteCRM data and configure the app layout.

trace = go.Bar(x=df.Name, y=df.Industry, name='Name')

app.layout = html.Div(children=[html.H1("CData Extension + Dash", style={'textAlign': 'center'}),
	dcc.Graph(
		id='example-graph',
		figure={
			'data': [trace],
			'layout':
			go.Layout(title='SuiteCRM Accounts Data', barmode='stack')
		})
], className="container")

Set the App to Run

With the connection, app, and layout configured, we are ready to run the app. The last lines of Python code follow.

if __name__ == '__main__':
    app.run_server(debug=True)

Now, use Python to run the web app and a browser to view the SuiteCRM data.

python suitecrm-dash.py
