Tableau Prep Builder uses TabPy to pass data from your flow through TabPy as the input, applies your script, then returns the results back to the flow.
Follow the installation and configuration instructions for installing TabPy.

To configure Tableau Server, see Configure the Tableau Python (TabPy) server for Tableau Server.įor information about how to configure sites on Tableau Server with analytics extensions for workbooks, see Configure Connections with Analytics Extensions. Running flows with script steps in Tableau Online, isn't currently supported. You can run flows that include script steps in Tableau Server as long as you have configured a connection to your TabPy server. When you add a script step to your flow and specify the configuration details, file, and function that you want to use, data is securely passed to the TabPy server, the expressions in the script are applied, and the results are returned as a table that you can clean or output as needed. Then you can use Python scripts to apply supported functions to data from your flow using a pandas dataframe. To include Python scripts in your flow, you need to configure a connection between Tableau and a TabPy server. By sending Python commands to an external service through Tableau Prep Builder, you can easily extend your data preparation options by performing actions like adding row numbers, ranking fields, filling down fields and performing other cleaning operations that you might otherwise do using calculated fields. Python is a widely used high-level programming language for general-purpose programming. For the most up-to-date information, please consult the python documentation and support. Please note that while we make every effort to keep references to third-party content accurate, the information we provide here might change without notice as python changes. You are now ready to develop your Django application.Disclaimer: This topic includes information about a third-party product. The folder structure should look like this in the end. Use the browser of you preference and navigate to will see the welcome screen of the Django project. You can start the Django application using the following command. python manage.py startapp app_nameīefore you start the application lets create a requirements.txt which contains all the installed packages (e.g. As before, please choose any name that you like. For this reason you need to create an app now. cd project_name/ĭjango has the concept of projects and apps. Navigate into the newly created project folder. Use any name that you like django-admin startproject project_name pip install djangoĪfter Django is installed you need to create a new project. You can now go ahead and install the latest Django version. This means you are now in your virtual environment. In the terminal you should now see the name of you virtual environment in brackets like this (virtural_environment_name). Use the following command source virtural_environment_name/bin/activate virtualenv -p python3 virtural_environment_nameĪfter that we need to activate the environment. The parameter -p python3 specifies that we want to use Python 3 in this virtual environment. Then create a new virtual environment via the terminal using the following command. You have all this? Then you are ready to go.įirst, navigate to the folder where you want to create you project. Prerequisites for this tutorial are: you have a Mac, you have Python 3 installed, you have virtualenv installed and you have pip installed. This is a quick tutorial on how to create a new Django project on a Apple Mac using Python 3 as a programming language.
