To limit the number of characters shown in a tree view for a text field in Odoo, you can use a combination of XML and Python. In Odoo tree views don\u2019t support truncating text directly in the XML view, but you can achieve this by modifying the field value in Python and displaying the truncated text in the tree view.<\/p>\n\n\n\n

Here\u2019s how you can do it:<\/p>\n\n\n\n

Step-by-Step Approach<\/h3>\n\n\n\n
    \n
  1. Add a Computed Field in Python<\/strong>:
    You can define a computed field in Python that truncates the text and show this field in the tree view. The computed field will contain a shortened version of the original text field. In your models.py<\/mark><\/code> file, define a computed field like this:<\/li>\n<\/ol>\n\n\n\n
       from odoo import models, fields\n\n   class YourModel(models.Model):\n       _name = 'your.model'\n\n       full_text = fields.Text('Full Text')  # The original text field\n       short_text = fields.Char(\n           string='Short Text',\n           compute='_compute_short_text',\n           store=False\n       )\n\n       def _compute_short_text(self):\n           for record in self:\n               if record.full_text:\n                   record.short_text = record.full_text[:50] + '...' if len(record.full_text) > 50 else record.full_text<\/mark><\/code><\/code><\/pre>\n\n\n\n
    In this example, the short_text<\/mark><\/code> field will show the first 50 characters of the full_text<\/mark><\/code> field followed by ellipsis (...<\/mark><\/code>) if the text is longer than 50 characters.<\/p>\n\n\n\n
      \n
    1. Update the Tree View XML<\/strong>:
      You\u2019ll now need to display the short_text<\/mark><\/code> field in the tree view. In your views.xml<\/mark><\/code>, update the tree view to use the short_text<\/mark><\/code> field instead of full_text<\/mark><\/code>:<\/li>\n<\/ol>\n\n\n\n
         <tree>\n       <field name=\"short_text\" string=\"Short Text\" \/>\n   <\/tree><\/mark><\/code><\/code><\/pre>\n\n\n\n
