Help with writing filters in custom script

[lxnow]

I have this script in sales order that filters the types of campaigns a user can choose depending on the customer_group of the customer, the date validity of the campaign, and the campaign approval status.  It currently looks like this:

cur_frm.fields_dict.tma_campaign.get_query = function(doc) {

    return {

filters: [

['Campaign', 'proposal_status', 'in', 'Approved'],

['Campaign', 'customer', 'in', doc.customer_group],

['Campaign', 'start_date', '<=', get_today()],

['Campaign', 'end_date', '>=' , get_today()]

]

}

}

I'd like to be able to add an OR type filter that lets me include another field that is normally mutually exclusive with the 'customer' field (bold line above); something like

['Campaign', 'national_campaign', '=', '1'],

The problem is that 'national_campaign' and 'customer' are mutually exclusive, i.e. if a campaign is 'national_campaign' = 1, then the 'customer' field would be null.

There are 2 way to do it:

1) Define a function in server side code which will return the desired output for campaign field. And call that function from inside get_query:

cur_frm.fields_dict.tma_campaign.get_query = function(doc) {

return {query: "path to server side function"}

}

2. You can define the desired query in custom client side script. In this case:

  cur_frm.fields_dict.tma_campaign.get_query = function(doc) {

return 'select name from tabCampaign where proposal_status="Approved" and (customer="' + doc.customer_group + '" or national_campaign = 1) and curdate() between start_date and end_date order by name';

}
