Hello Faizan,
There is no radio button widget available in v7.
You can get only drop down widget for both selection and many2one fields. However, in v8, there will be a new radio button widget that can be used in view using widget="radio" attribute.
The new radio widget is available now in trunk branch.
Thank you.
There is no radio button widget in v7, but you can add it using widget="radio" attribute.
First you create your own widget [like selection widget] then add python code and XML code like below:
Python Code :
'syllabus': fields.selection([('one','One'),('two','Two')],'Syllabus'),
XML Code :
<field name="syllabus" widget="radio"/>
Hope It Helps You More !!!
Thanks !
I think you mean this is possible only in v8.0 which is not released yet.
Create Sample module web_widget_radio
1) Required files
__init__.py
__openerp__.py
static/src/js/widget_radio.js
static/src/xml/widget_radio.xml
2) Add following in __openerp__.py
'js': ['static/src/js/widget_radio.js'],
'qweb': ['static/src/xml/widget_radio.xml'],
3) Add following code in static/src/xml/widget_radio.xml
<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
<t t-name="FieldRadio">
<span t-attf-class="oe_form_field oe_form_field_radio #{widget.options.horizontal ? 'oe_horizontal' : 'oe_vertical'}" t-att-style="widget.node.attrs.style">
<span t-if="!widget.get('effective_readonly')">
<t t-if="widget.options.horizontal">
<t t-set="width" t-value="Math.floor(100 / widget.selection.length)"/>
<t t-if="!widget.options.no_radiolabel">
<t t-foreach="widget.selection" t-as="selection">
<label t-att-for="widget.uniqueId + '_' + selection[0]" t-att-style="'width: ' + width + '%;'"><t t-esc="selection[1]"/></label>
</t>
<br/>
</t>
<t t-foreach="widget.selection" t-as="selection">
<div t-att-style="'width: ' + width + '%;'">
<span class="oe_radio_input"><input type="radio" t-att-name="widget.uniqueId" t-att-id="widget.uniqueId + '_' + selection[0]" t-att-value="selection[0]"/></span>
</div>
</t>
</t>
<t t-if="!widget.options.horizontal">
<html>
<tr>
<t t-foreach="widget.selection" t-as="selection">
<span class="oe_radio_input"><input type="radio" t-att-id="widget.uniqueId + '_' + selection[0]" t-att-name="widget.uniqueId" t-att-value="selection[0]"/></span><label t-if="!widget.options.no_radiolabel" t-att-for="widget.uniqueId + '_' + selection[0]"><t t-esc="selection[1]"/></label>
</t>
</tr>
</html>
</t>
</span>
<span t-if="widget.get('effective_readonly')" class="oe_radio_readonly"><t t-esc="widget.get('value')[1]"/></span>
</span>
</t>
</templates>
4) Add following code in static/src/js/widget_radio.js
openerp.web_widget_radio = function (instance)
{
instance.web.form.widgets.add('radio', 'instance.web_widget_radio.FieldRadio');
instance.web_widget_radio.FieldRadio = instance.web.form.AbstractField.extend(instance.web.form.ReinitializeFieldMixin, {
template: 'FieldRadio',
events: {
'click input': 'click_change_value'
},
init: function(field_manager, node) {
/* Radio button widget: Attributes options:
* - "horizontal" to display in column
* - "no_radiolabel" don't display text values
*/
this._super(field_manager, node);
this.selection = _.clone(this.field.selection) || [];
this.domain = false;
},
initialize_content: function () {
this.uniqueId = _.uniqueId("radio");
this.on("change:effective_readonly", this, this.render_value);
this.field_manager.on("view_content_has_changed", this, this.get_selection);
this.get_selection();
},
click_change_value: function (event) {
var val = $(event.target).val();
val = this.field.type == "selection" ? val : +val;
if (val == this.get_value()) {
this.set_value(false);
} else {
this.set_value(val);
}
},
/** Get the selection and render it
* selection: [[identifier, value_to_display], ...]
* For selection fields: this is directly given by this.field.selection
* For many2one fields: perform a search on the relation of the many2one field
*/
get_selection: function() {
var self = this;
var selection = [];
var def = $.Deferred();
if (self.field.type == "many2one") {
var domain = instance.web.pyeval.eval('domain', this.build_domain()) || [];
if (! _.isEqual(self.domain, domain)) {
self.domain = domain;
var ds = new instance.web.DataSetStatic(self, self.field.relation, self.build_context());
ds.call('search', [self.domain])
.then(function (records) {
ds.name_get(records).then(function (records) {
selection = records;
def.resolve();
});
});
} else {
selection = self.selection;
def.resolve();
}
}
else if (self.field.type == "selection") {
selection = self.field.selection || [];
def.resolve();
}
return def.then(function () {
if (! _.isEqual(selection, self.selection)) {
self.selection = _.clone(selection);
self.renderElement();
self.render_value();
}
});
},
set_value: function (value_) {
if (value_) {
if (this.field.type == "selection") {
value_ = _.find(this.field.selection, function (sel) { return sel[0] == value_;});
}
else if (!this.selection.length) {
this.selection = [value_];
}
}
this._super(value_);
},
get_value: function () {
var value = this.get('value');
return value instanceof Array ? value[0] : value;
},
render_value: function () {
var self = this;
this.$el.toggleClass("oe_readonly", this.get('effective_readonly'));
this.$("input:checked").prop("checked", false);
if (this.get_value()) {
this.$("input").filter(function () {return this.value == self.get_value();}).prop("checked", true);
this.$(".oe_radio_readonly").text(this.get('value') ? this.get('value')[1] : "");
}
}
});
};
5) Once files are created install the module.Once installation is complete you have done 80% of creating Radio button
6) Few more steps to get 100%
Create Selection field in your_python_file.py
IS_OBSTRUCTED = [ ('yes', 'YES'), ('no', 'NO'), ]
class your_module(osv.osv):
_name = "your.module"
_description = "Your module Description"
_columns = {
'is_obstructed':fields.selection(IS_OBSTRUCTED,'Obstructed View?'),
}
your_module()
Create filed view in XML
<field name="is_obstructed" widget="radio"/>
Thank u its working
i got it.. when i download the new version 8 from nightly.openerp.com/trunk/nightly/src/
and change the view file code to <field name="syllabus" widget="radio"/>
then radio btn appears..
thanks for your answers
Please, go to the first answer and set it as correct (click on grey circle that become green). Thanks.
How to assign a value for widget= radio using xml
It is possible follow this steps and achieve it.
Create file structure given below Create flolder and name web_widget_radio __init__.py __openerp__.py static/src/js/widget_radio.js static/src/xml/widget_radio.xml
Add these two lines in _openerp_.py 'js': ['static/src/js/widget_radio.js'], 'qweb': ['static/src/xml/widget_radio.xml'], Make _init_.py empty file
Add following code in static/src/xml/widget_radio.xml <templates id="template" xml:space="preserve"> <t t-name="FieldRadio"> <t t-if="widget.options.horizontal"> <t t-set="width" t-value="Math.floor(100 / widget.selection.length)"/> <t t-if="!widget.options.no_radiolabel"> <t t-foreach="widget.selection" t-as="selection"> <label t-att-for="widget.uniqueId + '_' + selection[0]" t-att-style="'width: ' + width + '%;'"><t t-esc="selection[1]"/></label> </t>
</t> <t t-foreach="widget.selection" t-as="selection"><input type="radio" t-att-name="widget.uniqueId" t-att-id="widget.uniqueId + '_' + selection[0]" t-att-value="selection[0]"/></t> </t> <t t-if="!widget.options.horizontal"> <html> <t t-foreach="widget.selection" t-as="selection"> <input type="radio" t-att-id="widget.uniqueId + '_' + selection[0]" t-att-name="widget.uniqueId" t-att-value="selection[0]"/><label t-if="!widget.options.no_radiolabel" t-att-for="widget.uniqueId + '_' + selection[0]"><t t-esc="selection[1]"/></label> </t> </html></t> </span> <span t-if="widget.get('effective_readonly')" class="oe_radio_readonly"><t t-esc="widget.get('value')[1]"/></span> </span></t> </templates>
Add following script in static/src/js/widget_radio.js openerp.web_widget_radio = function (instance) { instance.web.form.widgets.add('radio', 'instance.web_widget_radio.FieldRadio'); instance.web_widget_radio.FieldRadio = instance.web.form.AbstractField.extend(instance.web.form.ReinitializeFieldMixin, { template: 'FieldRadio', events: { 'click input': 'click_change_value' }, init: function(field_manager, node) { /* Radio button widget: Attributes options: * - "horizontal" to display in column * - "no_radiolabel" don't display text values / this._super(field_manager, node); this.selection = _.clone(this.field.selection) || []; this.domain = false; }, initialize_content: function () { this.uniqueId = _.uniqueId("radio"); this.on("change:effective_readonly", this, this.render_value); this.field_manager.on("view_content_has_changed", this, this.get_selection); this.get_selection(); }, click_change_value: function (event) { var val = $(event.target).val(); val = this.field.type == "selection" ? val : +val; if (val == this.get_value()) { this.set_value(false); } else { this.set_value(val); } }, /* Get the selection and render it * selection: [[identifier, value_to_display], ...] * For selection fields: this is directly given by this.field.selection * For many2one fields: perform a search on the relation of the many2one field */ get_selection: function() { var self = this; var selection = []; var def = $.Deferred(); if (self.field.type == "many2one") { var domain = instance.web.pyeval.eval('domain', this.build_domain()) || []; if (! _.isEqual(self.domain, domain)) { self.domain = domain; var ds = new instance.web.DataSetStatic(self, self.field.relation, self.build_context()); ds.call('search', [self.domain]) .then(function (records) { ds.name_get(records).then(function (records) { selection = records; def.resolve(); }); }); } else { selection = self.selection; def.resolve(); } } else if (self.field.type == "selection") { selection = self.field.selection || []; def.resolve(); } return def.then(function () { if (! _.isEqual(selection, self.selection)) { self.selection = _.clone(selection); self.renderElement(); self.render_value(); } }); }, set_value: function (value_) { if (value_) { if (this.field.type == "selection") { value_ = _.find(this.field.selection, function (sel) { return sel[0] == value_;}); } else if (!this.selection.length) { this.selection = [value_]; } } this._super(value_); }, get_value: function () { var value = this.get('value'); return value instanceof Array ? value[0] : value; }, render_value: function () { var self = this; this.$el.toggleClass("oe_readonly", this.get('effective_readonly')); this.$("input:checked").prop("checked", false); if (this.get_value()) { this.$("input").filter(function () {return this.value == self.get_value();}).prop("checked", true); this.$(".oe_radio_readonly").text(this.get('value') ? this.get('value')[1] : ""); } } }); }; Finally save all files and restart server and install this module once get installed
- How to use it in your view Create module and open your ______________.py file Create selection field IS_OBSTRUCTED = [ ('yes', 'YES'), ('no', 'NO'), ]
Finally OpenERP 7.0 allows you to create radio button
