Hi dear ones,

To remove options from an odoo 15 selection field, proceed as follows:

Example:

Basic model

class SurveyQuestion(models.Model):
​_name = 'survey.question'

​question_type = fields.Selection([
('text_box', 'Multiple Lines Text Box'),
('char_box', 'Single Line Text Box'),
('numerical_box', 'Numerical Value'),
('date', 'Date'),
('datetime', 'Datetime'),
('simple_choice', 'Multiple choice: only one answer'),
('multiple_choice', 'Multiple choice: multiple answers allowed'),
('matrix', 'Matrix')], string='Question Type',
compute='_compute_question_type', readonly=False, store=True)

*****************************************************************************

Inheritance model

class SurveyQuestionInherited(models.Model):
​_inherit = 'survey.question'

question_type = fields.Selection(selection='_get_new_question_type', string='Type de question', compute='_compute_question_type', readonly=False, store=True)

@api.model
def _get_new_question_type(self):
"""Cette methode permet de mettre à jour les types de question,
Dans le but de retirer les options 'multiple_choice' et 'matrix'
"""
selection = [
('text_box', 'Zone de texte à plusieurs lignes'),
('char_box', 'Zone de texte sur une seule ligne'),
('numerical_box', 'Valeur numérique'),
('date', 'Date'),
('datetime', 'Date et heure'),
('simple_choice', 'Choix multiple : une seule réponse')
]
return selection

After several unsuccessful attempts, this method worked for me.

I really hope it helps !

thank you but i need to delete this by key '6' not by index number

Hi adel,

you can use this code:

lst= [('5', '5'), ('6', '6'), ('7', '7'), ('8', '8')]
j=0
for i in lst:
	if i[0]=='6':
		del lst[j] 
		print lst
	j=j+1
result: [('5', '5'), ('7', '7'), ('8', '8')]
