Search form not working using class based view - django-class-based-views

I'm trying to create a search form but it's not working. Here are my codes:
class LocationSearchMixin(object):
def get_queryset(self):
q = self.request.GET.get('q')
if q is None:
return queryset
class StoreListView(LocationSearchMixin, ListView):
model = Store
<form action="" method="GET">
<input type="text" name="q" />
<button type="submit">search</button>
</form>

There are something you must add in your LocationSearchMixin:
class LocationSearchMixin(object):
def get_queryset(self):
queryset = super(LocationSearchMixin, self).get_queryset()
q = self.request.GET.get('q')
if q is None:
return queryset
return queryset.filter(location__istartswith=q)

#Edit
i'm using grails 3.1.6 and where's my url mapping:
package eventosunipar
class UrlMappings {
static mappings = {
"/$controller/$action?/$id?(.$format)?"{
constraints {
// apply constraints here
}
}
"/"(view:"/index")
"500"(view:'/error')
"404"(view:'/notFound')
}
}
<g:actionSubmit value="Salvar"/> - actionSubmit is a button to submit to different actions from single form as stated in documentation: http://docs.grails.org/3.1.1/ref/Tags/actionSubmit.html If action parameter is not set in this button, it defaults to value, in your case Salvar. Add action="save" to your button definition or use standard <input type="submit" ... /> tag (I would suggest this option).
If this doesn't work, show generated HTML of the page with form from your browser

An HTML form reset button for a form rests the form to the initial state. In this case back to the values it had when the form loaded. A HTML form reset button does not CLEAR the form or CLEAR the session.
wondering why you are using session for where typicalls form params should be used? In order to clear HTML session you would need to trigger a call back to the originating controller just like you would to post but when it receives via this call. It does a session.invalidate() and then renders same view again. You should try to stick with params for forms. The fact that you have the session information already really no need to post it via a form. Your controller receiving the form would be aware of that same session value.
You could easily create a jquery functionality that you do with a button that triggers and a resetform. jQuery/Javascript function to clear all the fields of a form
Or if that does not work you could try for example in your case:
<g:form ..>
..
<button onClick="clearName();" name="clickme">
</g:form>
<g:javascript>
function clearName() {
$('#name').val();
}
</g:javascript>

Can't route my input parameters to my controller action method

I'm having trouble passing my textbox data to a controllers action parameters.
I'm trying to get the url to look like:
http://localhost:51124/gifts?searchTerm=test
but when I enter in text into the text box I get a url that looks like:
http://localhost:51124/gifts
Here is the code I have for the route:
routes.MapRoute("Gifts",
"gifts",
new { controller = "Gifts", action = "Search" });
here is the code for the page with the text box and button to submit the text box data:
<form method="GET">
<input type="search" name="searchTerm"/>
<input type="button" value="Search By Category" onclick="location.href='#Url.Action("Search", "Gifts")'" />
</form>
here is the code for the controller that I'm trying to pass data to unsuccessfully:
public ActionResult Search(string searchTerm = null)
{
var model = db.Gifts.ToList();
return View(model);
}
"searchTerm" never gets any parameter that I pass into the text box. It's always null.
Create a form element in you view with an input (i.e. the search box) that has a name attribute matching the parameter and a submit button.
#using (Html.BeginForm("Search", "Gifts") {
<input type='text' name='searchTerm' value='' />
<input type='submit' value='search' />
}
This will post back to the Search method in the Gifts controller, passing the vale of the search box to the parameter 'searchTerm'
you have to build this with jquery. add a class to the inputs to use as a selector
<input type="search" name="searchTerm" class="txtSearch" />
<input type="button" value="Search By Category" class="btnSearch" />
then in your script
$('.btnSearch').on('click', function(){
var url = '#Url.Action("Search", "Gifts", new { searchTerm = "----" })'.replace("----", $('.txtSearch').val());
window.location(url);
});

Creating a view with Domain object fields

I have the following domain classes.
Address
String number
String roadName
String country
Person
String fName
String age
Address address
I have a view called PersonViewSave i want the user to be able to save Person information from this view. When creating a Person record the user needs to create a Address record as well.
My Person controller looks like this:
PersonViewSave ={
def ad = new Address(number: '11', roadName: 'round road', country:'France').save()
new Person(fName: 'Alex', age: '23', address:ad).save()
}
1.) How do i collect parameters from the view and bring it to the PersonViewSave method ? (And can someone show me a sample GSP view file with the Person and Address textfields)
2.) Incase if there's an error in the Address created, how do i prevent creating a Person object with an address as shown in this line new Person(fName: 'Alex', age: '23', address:ad).save()
UPDATE
<g:form name="myForm" method="post" action="doIt">
<p>Person info:</p>
<label for="firstName">First Name</label>
<g:textField name="firstName" id="firstName" />
<p>Address Info:</p>
<label for="roadName">Street Number</label>
<g:textField name="roadName" id="roadName" />
<g:submitButton name="submit" value="Submit" />
Here, i have only used few objects from the Domain classes just to see if it works.
I also have a parameter called createdDate in both Domain classes. That as well needs to be auto inserted.
My Service Class is as follows:
def saveService () {
def ad = new Address(params)
if (ad.save(flush: true)) {
def p = new Person(params)
p.address = ad
p.save()
} else {
// display validation errors
}
}
1.) I get an error and it is > No such property: params for class: pro.PersonService
2.) What hapence i have 2 domain class with parameters that has the same Name. For example Animal and Person domain classes have an parameter called firstName. According to your previous solution how will grail distinguish to what domain class it belongs to ?
I am using Grails 2.2.4
Here is a way to check that the Address saved correctly:
def ad = new Address(params)
if (ad.save(flush: true)) {
def p = new Person(params)
p.address = ad
p.save()
} else {
// display validation errors
}
This returns the Address if it saved properly, which results in true, otherwise it returns null (or false).
Also, you can use data binding via the params map to create your objects from parameters. As long as the key in params matches up to a property name in your Address and Person class, the value of the parameter will be assigned to the object.
So, for instance, to map your Person, you will need fields like the following:
<g:form name="personForm" method="post" action="PersonViewSave">
<p>Person info:</p>
<label for="fName">First Name</label>
<g:textField name="fName" id="fName" />
<label for="age">Age</label>
<g:textField name="age" id="age" />
<p>Address Info:</p>
<label for="number">Street Number</label>
<g:textField name="number" id="number" />
<label for="roadName">Road</label>
<g:textField name="roadName" id="roadName" />
<label for="country">Country</label>
<g:textField name="country" id="country" />
<g:submitButton name="submit" value="Submit" />
</g:form>
you can try this
def ad = new Address(number:params.number , roadName:params.roadName , country: params.country)
if (ad.save(flush: true)) {
def p = new Person(fName:params.fName , age: params.age, address:ad)
p.save()
} else {
// display validation errors
}

Grails databinding multiple domain classes

HI. I have this classes:
class Carro {
String name
String marca
String matricula
static constraints = {
name(nullable:false, blank:false)
}
static mapping = {
version false
}
}
class CarroMovel {
String move
String rodas
String espelhos
Carro carro
static hasMany = [carros: Carro]
static constraints = {
move(nullable:false, blank:false)
}
static mapping = {
version false
}
}
And the controllers:
class CarroController{
def save2 = {
def carroInstance = new Carro()
carroInstance.name = params.name
carroInstance.marca = params.marca
carroInstance.matricula = params.matricula
if (carroInstance.save(flush: true)) {
redirect(uri:"/home.gsp")
}
else {
render(view: "/testeAdd", model: [carroInstance: carroInstance])
}
}
And the view testeAdd.gsp
<g:form controller="carro" action="save2">
<h1>Add New Carro Record</h1>
<p>Basic Information</p>
<label>Name
<span class="small">as</span>
</label>
<input type="text" name="name" value="${carroInstance?.name}" /><br>
<label>Marca
<span class="small">as</span>
</label>
<input type="text" name="marca" value="${carroInstance?.marca}" /><br
<label>Matricula
<span class="small">as</span>
</label>
<input type="text" name="matricula" value="${carroInstance?.matricula}" /><br>
<g:submitButton name="save" value="Save" id="oneone"/>
<div class="spacer"></div>
</g:form>
<g:hasErrors bean="${carroInstance}">
<div class="errors">
<g:renderErrors bean="${carroInstance}" as="list" />
</div>
</g:hasErrors>
This is working good. Now i would like to be able to data binding multiple domain classes. So, along with the current code from my gsp file, i would also like to add carroMovel occurrences all in same save2. Im not sure how to do that, specially cause class Carro will need to have an id from class carroMovel. Any help please? Thank you.
I folowed some suggestions and now the results are as follows (im not concerned about error validation yet):
def save3 = {
def carroInstance = new Carro()
def carroMovelInstance = new CarroMovel()
carroInstance.name = params.carro.name
carroInstance.marca = params.carro.marca
carroInstance.matricula = params.carro.matricula
carroMovelInstance.move = params.carroMovel.move
carroMovelInstance.rodas = params.carroMovel.rodas
carroMovelInstance.espelhos = params.carroMovel.espelhos
carroInstance.save()
carroMovelInstance.carro = carroInstance
carroMovelInstance.save()
}
<g:form controller="carro" action="save3">
<h1>Add New Conference Record</h1>
<p>Basic Information</p>
<label>Name
<span class="small">Add your name</span>
</label>
<input type="text" name="carro.name" value="${carroInstance?.name}" /><br>
<label>Marca
<span class="small">Add your name</span>
</label>
<input type="text" name="carro.marca" value="${carroInstance?.marca}" /><br
<label>Matricula
<span class="small">Add your name</span>
</label>
<input type="text" name="carro.matricula" value="${carroInstance?.matricula}" /><br>
<label>Move
<span class="small">Add your name</span>
</label>
<input type="text" name="carroMovel.move" value="${carroMovelInstance?.move}" /><br>
<label>Rodas
<span class="small">Add your name</span>
</label>
<input type="text" name="carroMovel.rodas" value="${carroMovelInstance?.rodas}" /><br>
<label>Espelho
<span class="small">Add your name</span>
</label>
<input type="text" name="carroMovel.espelho" value="${carroMovelInstance?.espelho}" /><br>
<g:submitButton name="save" value="Save" id="addConference"/>
The Carro object is saved in the database, altought, nothing happens with CarroMovel and it is not saved and i can't figure it out.
First I would change the input names to carro.name, carro.marca, carroMovel.move, ... so that they are differentiated by name.
<input type="text" name="carro.name"/><br>
<input type="text" name="carro.marca"/><br>
<input type="text" name="carroMovel.move"/><br>
This has the advantage that the binding in the controller can be done the standard Grails way, and that the correct values are entered in the form without the value attribute set.
carro.properties = params.carro
carroMovel.properties = params.carroMovel
In the controller action you can also save and link the Carro and CarroMovel instances.
carro.save()
carroMovel.carro = carro
carroMovel.save()
if(carroMovel.hasErrors(){
render(view: 'save3', model: [carro: carro, carroMovel.carroMovel])
}
If I understand your question correctly, you can give this a try.
First, edit our form to include the necessary fields for the CarroMovel class,
e.g
<label>Move
<span class="small">as</span>
</label>
<input type="text" name="move" value="${carroMovelInstance?.move}" />
then
in your save2 action,
def carroInstance = new Carro()
carroInstance.name = params.name
carroInstance.marca = params.marca
carroInstance.matricula = params.matricula
def carroMovelInstance = new CarroMovel()
carroMovelInstance.name = params.move
carroMovelInstance.marca = params.rodasa
carroMovelInstance.matricula = params.espelhos
carroMovelInstance.carro = carroInstance
Since Carro does not belong to CarroMovel saving a carroMovelInstance will not cascade to the carroInstance, therefore you will need to save each instance individually before saving its owning instance.
carroMovelInstance.carro.save()
if (carroMovelInstance.save(flush: true)) {
redirect(uri:"/home.gsp")
}
else {
render(view: "/testeAdd", model: [carroInstance: carroInstance, carroMovelInstance:carroMovelInstance])
}
Let me know if that works out for you.
Some of the other answers may be simpler, but I've been using this technique:
http://omarello.com/2010/08/grails-one-to-many-dynamic-forms/
In order for Carro to cascade save the CarroMovel reference, CarroMovel needs belongsTo = Carro or you need to manually tell hibernate to cascade it upon save using something like this:
class CarroMovel{
static mapping = {
carro cascade: 'all'
}
}
Here's the hibernate documentation about cascading:
https://docs.jboss.org/hibernate/orm/4.0/javadocs/org/hibernate/metamodel/binding/CascadeType.html
I usually use a command object for this type of thing.
In your controller do something like this:
class CarroController {
def show = {
[cmd: new MyCommand()]
}
def save2 = { MyCommand cmd ->
def carro = cmd.carro
if (carro.save()) {
cmd.movel.carro = carro
if (cmd.movel.save()) {
redirect uri: 'home.gsp'
} else {
// show form again
render view: 'show', model:[cmd:cmd]
}
} else {
// show form again
render view: 'show', model:[cmd:cmd]
}
}
// same file or some other class file
class MyCommand {
Carro carro
CarroMovel movel
}
}
You will need to adjust your form a bit as well...
Where you have "Carro" fields reference them like this:
<input type="text" name="carro.matricula" value="${cmd.carro?.matricula}" />
Where you have the "CarroMovel" fields, like this:
<input type="text" name="movel.rodas" value="${cmd.movel?.rodas}" />
This code might not be exactly right (I didn't test it), but should get you down the correct path. Also instead of referencing the objects in the command object, you could just have the fields that you are binding, and then build the actual domain objects from them, either through a helper method (def buildCarro(){...}) or by hand in the controller method.
