Python generator integration error

[VINDER DEVGAN]

Hi all,

We have old setup of blockly and javascript_compressed generator file and its working fine. and i have downloaded the latest python_compressed file to generate python code but unfortunately i'm get this error :

Uncaught TypeError: Cannot read property 'call' of undefined

on calling this function window.Blockly.Python.workspaceToCode(workspace).

and i have notice difference in between javascript and python compressed file the init function is using this keyword and i guess this may be not working due to different vesion. could you please give me solution to fix it

compressed file init function code

Blockly.JavaScript.init = function (a) {

  Blockly.JavaScript.definitions_ = Object.create(null);

  Blockly.JavaScript.functionNames_ = Object.create(null);

  Blockly.JavaScript.variableDB_

    ? Blockly.JavaScript.variableDB_.reset()

    : (Blockly.JavaScript.variableDB_ = new Blockly.Names(

        Blockly.JavaScript.RESERVED_WORDS_

      ));

  var b = [];

  a = a.getAllVariables();

  if (a.length) {

    for (var c = 0; c < a.length; c++)

      b[c] = Blockly.JavaScript.variableDB_.getName(

        a[c].name,

        Blockly.Variables.NAME_TYPE

      );

    Blockly.JavaScript.definitions_.variables = "var " + b.join(", ") + ";";

  }

};

Blockly.Python.init = function (a) {

  Object.getPrototypeOf(this).init.call(this);

  this.PASS = this.INDENT + "pass\n";

  this.nameDB_

    ? this.nameDB_.reset()

    : (this.nameDB_ = new Blockly.Names(this.RESERVED_WORDS_));

  this.nameDB_.setVariableMap(a.getVariableMap());

  this.nameDB_.populateVariables(a);

  this.nameDB_.populateProcedures(a);

  for (

    var b = [], c = Blockly.Variables.allDeveloperVariables(a), d = 0;

    d < c.length;

    d++

  )

    b.push(

      this.nameDB_.getName(c[d], Blockly.Names.DEVELOPER_VARIABLE_TYPE) +

        " = None"

    );

  a = Blockly.Variables.allUsedVarModels(a);

  for (d = 0; d < a.length; d++)

    b.push(

      this.nameDB_.getName(a[d].getId(), Blockly.VARIABLE_CATEGORY_NAME) +

        " = None"

    );

  this.definitions_.variables = b.join("\n");

  this.isInitialized = !0;

};

i have found the solution by replacing python_compressed code old python compressed
