How set readOnly dynamically in record.js?

You should be able to adapt this Gist to do what you want:

Custom record view controller for setting entire record to read-only conditionally · GitHub

They key is to add the field name into the "noEditFields" array.

Hi
This code works for me in 7.8 when I pause it at breakpoints. However it appears that this javascript is running before the model has been loaded, hence I get
 this.model.attributes.sales_status is undefined
When I run it without breakpoints.

When I insert a breakpoint and type in the javascript console
this.model.attributes.sales_status
It comes up with "Closed Won", but when I have
console.log(this.model.attributes.sales_status)
it just prints undefined.
Is there a way to make sure this only runs once the model has been fully loaded?

Also is it preferred to set fields to readonly using this method or sugarlogic dependencies?

You would want to wait for the data:sync:complete event to fire.

Here is an example of its use:

Custom record view controller, changes CSS on a given field based on number of subpanel child records linked to current … 

Hi,

Try 

 this.$('.record-edit-link-wrapper[data-name=' + field.name + ']').remove();
instead of
self.noEditFields.push(field.name); As this will not work on 7.8.. versions.

Also disable edit and save action.
$('.headerpane a[name=edit_button]').addClass("disabled");
$('.headerpane a[name=save_button]').addClass("disabled");
var self = this;
_.each(this.model.fields, function(field) {
    //self.noEditFields.push(field.name);
    this.$('.record-edit-link-wrapper[data-name=' + field.name + ']').remove();
},this);
