Script Coding - Project/Task Creation Script Example

Hi everyone, I found this very good script template, and need help with some adjustements please.

“Collaborators” used to be a dependency field, called “Followed By”, but I would like to use this field rather to assign collaborator names, that are stored in a separate sheet called “Collaborators”.

The purpose of the Base is to automatically assign tasks and collaborator names to classes.

Here is the code:

// when a new asset is created,
// there are a certain number of tasks that must be completed
// these tasks are dependent on the type of asset
// Given a list of project and task templates,
// when a new asset is created and has a project template assigned
// we can then create corresponding set of tasks for that asset

// define some of our initial variables
// these are the basic table, field and view names to define to create the script
const project_table_name = ‘Classes’;
const new_project_view_name = ‘New Projects’;
const project_template_link_field_name = ‘Project Template’;

const task_table_name = ‘Tasks’;
const task_project_link_field_name = ‘Classes’;
const task_dependency_field_name = ‘Collaborators’;
const task_primary_field_name = ‘Task Name’;

const task_to_template_link_field_name = ‘_task_template_id’; // this is used to assist with creating the links between tasks after they are created. We don’t need to maintain a true linked record relationship, but temporarily storing the template’s ID is helpful

const project_template_table_name = ‘Project Templates’;
const task_template_table_name = ‘Task Templates’;
const proj_temp_task_temp_link_field_name = ‘Tasks’;
const task_temp_dependency_field_name = ‘Collaborators’;
const task_temp_primary_field_name = ‘Task Name’;

Here is a link to the Base, that also has the code and the new sheets that I want to use. I would appreciate if someone could have a look, and try to fix that the Collaborator field also gets field when tasks are being created; Sign up - Airtable

@Giovanni_Briggs any chance you could help?
