Normally the form view in edit mode will displayed if you give 'target': 'inline', in action params.

Please check your action and if not the case try to give the view_id.

Hi, if you are using JS or you are returning an action to open the form you can add `flags` for this, unfortunately there is no `flags` field in the python model of `ir.action.act_window`.

JS:

 var action = {
                type: 'ir.actions.act_window',
                name: 'Action Name',
                target: 'new', //use 'current' for not opening in a dialog
                res_model: 'target.model',
                res_id: target_id,
                view_id: 'view_xml_id',//optional
                view_type: 'form',
                views: [[false,'form']],
                context: {//your context
                         },
                flags:{
                mode:'readonly'
                } // default is 'edit'
            };
        this.do_action(action);
 

in python code (assuming that your button has `type='object'`):

@api.multi

def your_button_name(self):

return {

                'type': 'ir.actions.act_window',
                'name': 'Action Name',
                'target': 'new', #use 'current' for not opening in a dialog
                'res_model': 'target.model',
                'res_id': target_id,
                'view_id': 'view_xml_id',#optional
                'view_type': 'form',
                'views': [[false,'form']],
                'context': {#your context
                         },
                'flags':{mode:'readonly'} # default is 'edit'
            };

Thank for the reply,

Please excuse me I think I have not well explained my problem, I already"<field name="view_mode">kanban,form,tree</field>"

On the Kanban view, when I click on a record, the form opens but directly in edit mode, I would like it to open in view mode,

I have the same problem on a calendar view.

Thanks

Hi, Joaquim lozano

     You have to change the "Action window" of your current model and there will be one field like,

"<field name="view_mode">tree,form</field>"

    you have to change the view mode's priority. at there tree view must be first and second form view. Tree view is for display the data and form view is for edit the data.

I hope this will help you.
