Final answer:
When you use the same field name in a template that is already used in a parent template, it can lead to conflicts and errors. To avoid this, it is recommended to use unique field names in templates.
Step-by-step explanation:
When you use the same field name in a template that is already used in a parent template, it can lead to conflicts and errors. This is because the child template inherits the fields and behavior of the parent template. If you use the same field name, it can cause ambiguity and make it difficult for the template to determine which field to use.
For example, let's say the parent template has a field named 'name' which is used to display a person's name. If the child template also has a field named 'name' and you try to access it, there may be a conflict as the template may not be able to differentiate between the two fields.
To avoid this issue, it is recommended to use unique field names in templates, especially when working with inheritance. You can choose more descriptive names or prefix the field name with the template name to make it unique.
