How to create UML Diagrams in Pycharm Community Edition?

Question

Is it that one can you only create class diagrams in Pycharm Professional Edition? I have Pycharm Community Edition 2019.2 and I have installed the PlantUML plugin and Graphviz, also set the environment variables as required but still I cant create the Class diagram.

Generating UMLs from class in PyCharm is included by default. Maybe you have disabled them. Go to File -> Settings -> Plugins and search UML. There should be Python UML diagrams and UML which should have bundled keyword written below.

You can right click on class and and choose Diagrams to generate it.

For example, this class:

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

is represented as this:

For PlantUML plugin, you don't have to install anything except the plugin itself. When you install it, you can create new PlantUML file and select default diagram to be generated.

Solution 2

Based on searching online, I think the specific answer to your question is yes, you can only use the integrated UML plugins for Professional Edition. To do it for Community Edition, as Dinko said you would have to use the 3rd party plugin PlantUML.

Hi. I installed the 3rd party plugin PlantUML. I restart the PyCharm but i still do not have the option "Diagram" when I click in a python script.

Nothing like Python UML plugin is bundled with the community edition of PyCharm

You have to install PlantUML plugin to be able to create UML diagrams.

Yeah, the question and my answer are little out of sync. The question states "How to create UML diagrams in Pycharm Community Edition?" and I provided answer how to create it with PyCharm Pro and PyCharm community. However, with PlantUML you can create UML diagrams but only using PlantUML syntax. UMLs are shown in PyCharm, it's only when you edit your Python Class, you must edit also PlantUML file. Unfortunately, there is no option to generate diagram using PlantUML as in PyCharm Pro.

Yes I get it but the first part of your answer deals only with the Professional Edition of PyCharm.
