Blockly.Python is undefined

[Julia]

Hi!

I updated Blockly from 7.20211209.4 to 9.0.0.

Now I've got an error: Blockly.Puthon is undefined.

This is the way my blocks was defined: 

  Blockly.Blocks['can_forward'] = {

    init: function() {

      let input = this.appendDummyInput('can_forward')

        .appendField(this.getText('can_forward'))

      input.getText = () => this.getText('can_forward')

      this.setColour('#838CD8')

      this.setTooltip('')

      this.setHelpUrl('')

      this.setPreviousStatement(false)

      this.setNextStatement(false)

      this.setOutput(true, 'Boolean')

    }

  }

  Blockly.Python['can_forward'] = function(block) {

    return [Blockly.getCode('can_forward') + "()", Blockly.Python.ORDER_NONE]

  }

`getText` -- is some custom method for Block, doesn't matter.

 The problem is (at line with Blockly.Python): 

TypeError: Cannot set properties of undefined (setting 'can_forward')   

What am I doing wrong?

Hello!

Before 9.0.0 the built-in generators were added to the `Blockly` object as side effects when you imported them. But this no longer happens. Instead you need to import them directly like:

```

import {pythonGenerator} from 'blockly/python';

```

You can run the @blockly/migrate script to automatically fix your imports =)

Eg:

```

npx @blockly/migrate fix-imports --from 7 ./path/to/my/files/*

```

I hope that helps! If you have any further questions please reply =)

Hello, Beka! Thanks for your reply!

Unfortunately  @blockly/migrate script did nothing for me. I can't understand why.
Thanks for explainig about pythonGenerator.

As I understand it, the example in the documentation is no longer relevant?

Hello!

Yes it looks like those docs are slightly out of date =) I've put up a fix internally and it should be up in a few days!

Thank you for bringing this to the core team's attention =)

Best wishes,
