These settings are in.
In, you can set different settings for QGIS Server :
Short name is a machine readable name for the layer.
dataUrl is the URL to a HTML or PDF presenting the data. It can be a link to the open data portal webpage.
If the link is empty indialog, the link in Lizmap will be automatically populated by the Lizmap plugin from set in this tab.
You can use the button in Lizmap to pick this value.
Usually, the field names are defined without accent, spaces and can’t be very long. Inand clicking on a field, you can add an alias.
This will be used to substitute the field name when possible for a more friendly name.
, you can the list of alias defined on the layer.
Inand clicking on a field, you can setup the form.
To set the editing tools for your layer fields:
By selecting first a field on left panel, select the Widget type:
To hide a field, choose Hidden. The user will not see the field in the form. There will be no content inserting. Use it for the primary key.
To add a read-only field, unchecked Editable checkbox.
Special case of the option Value Relation. You can use this option for a Lizmap map. For users to have access to information of the outer layer that contains the data, you must enable the publication of the layer as a WFS layer in .
Lizmap Web Client does not know the “QT Designer UI file” for form generation. Therefore only use the Autogenerate mode or Drag and drop mode for editing layers.
To make the field compulsory you have to define it as
NOT NULL in the properties of the table,
in the database, not in QGIS –> Layer Properties.
All the editing tools are not yet managed by Lizmap Web Client. Only the following tools are supported:
If the tool is not supported, the web form displays a text input field.
To group fields in different tabs, follow the QGIS documentation about the drag and drop form.
Lizmap can reproduce several behavior configured in QGIS :
- Control visibility by expression.
For example, you can toggle tab’s visibility based on a checkbox state.
Create a field named
has_photodefined as a Checkbox widget
Control Visibility by Expression checked
"has_photo" = true OR "has_photo" = 't'
- Constraints defined by expression.
For example, you want to simply assert users correctly type a website URL beginning by http (of course, a regular expression would be better but we keep it simple).
Create a field named
websitedefined as a Text Edit widget
Define the Constraints
left( "website", 4) = 'http'
Expression description with
Web site URL must start with 'http'
- Filter expression for a Value Relation field.
For example, you want a field to automatically get the related value from another layer’s field when drawing a point on the map.
Create a field name
quartier(neighbourhood in French) defined as a Value Relation widget
Set the parent layer to another layer
Set Filter expression with
We can also check Not null and Enforce not null contraint to assert no NULL value can be set.
As shown in the video above, it’s not possible anymore, natively, to have the combobox showing the area clicked automatically after the click on the map. The combobox has an empty value as a first item but has still a single value in the dropdown menu with the name of the neighbourhood clicked on the map.
For PostGIS layers, you can enable server side simplification. This infor each layers. You can change the default behavior for next new layer in .
