    <p>I understand form the documentation <a href="http://docs.djangoproject.com/en/dev/ref/models/fields/" rel="nofollow">http://docs.djangoproject.com/en/dev/ref/models/fields/</a> that you can add error_messages to a model field and supply your own dict of error messages. However, what are they keys of the dict you are supposed to pass?</p> <pre><code>class MyModel(models.Model): some_field = models.CharField(max_length=55, error_messages={'required': "My custom error"}) </code></pre> <p>If it is easier to do this on the modelform that is used that would also work, however. I would rather not have to create explicitly creating each field and their type again. This is what I was trying to avoid:</p> <pre><code>class MyModelForm(forms.ModelForm): some_field = forms.CharField(error_messages={'required' : 'Required error'}) </code></pre> <p><strong>Update 2:</strong> Test code used in my project</p> <p>My Model:</p> <pre><code>class MyTestModel(models.Model): name = models.CharField(max_length=127,error_messages={'blank' : 'BLANK','required' : 'REQUIRED'}) </code></pre> <p>My Form:</p> <pre><code>class EditTestModel(ModelForm): class Meta: model = MyTestModel </code></pre> <p>My View:</p> <pre><code>tf = EditTestModel({'name' : ''}) print tf.is_valid() # prints False print tf.full_clean() # prints None print tf # prints the form, with a &lt;li&gt; error list containg the error "This field is required" &lt;tr&gt;&lt;th&gt;&lt;label for="id_name"&gt;Name:&lt;/label&gt;&lt;/th&gt;&lt;td&gt;&lt;ul class="errorlist"&gt;&lt;li&gt;This field is required.&lt;/li&gt;&lt;/ul&gt;&lt;input id="id_name" type="text" name="name" maxlength="127" /&gt;&lt;/td&gt;&lt;/tr&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
