I've encountered a problem while trying to list the users in the table using dataTable.
So far everything is working fine but when I enter more than 10 users, it still shows me 10 rows and can't view more than 10 rows. I've been trying to use the show by 10 25 50 100 entries but still can't work.
Here is the screen shot of the function that i've been trying to use:
This is the table that i use:
$(document).ready(function() {
$('table.dataTable').dataTable();
} );
This is my domain:
class Pilot {
String fName
String lName
static constraints = {
}
}
Here is the Controller:
class PilotController {
static allowedMethods = [save: "POST", update: "POST", delete: "POST"]
def index() {
redirect(action: "list", params: params)
}
def list(Integer max) {
params.max = Math.min(max ?: 10, 100)
[pilotInstanceList: Pilot.list(params), pilotInstanceTotal: Pilot.count()]
}
def create() {
[pilotInstance: new Pilot(params)]
}
def save() {
def pilotInstance = new Pilot(params)
if (!pilotInstance.save(flush: true)) {
render(view: "create", model: [pilotInstance: pilotInstance])
return
}
flash.message = message(code: 'default.created.message', args: [message(code: 'pilot.label', default: 'Pilot'), pilotInstance.id])
redirect(action: "show", id: pilotInstance.id)
}
def show(Long id) {
def pilotInstance = Pilot.get(id)
if (!pilotInstance) {
flash.message = message(code: 'default.not.found.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
redirect(action: "list")
return
}
[pilotInstance: pilotInstance]
}
def edit(Long id) {
def pilotInstance = Pilot.get(id)
if (!pilotInstance) {
flash.message = message(code: 'default.not.found.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
redirect(action: "list")
return
}
[pilotInstance: pilotInstance]
}
def update(Long id, Long version) {
def pilotInstance = Pilot.get(id)
if (!pilotInstance) {
flash.message = message(code: 'default.not.found.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
redirect(action: "list")
return
}
if (version != null) {
if (pilotInstance.version > version) {
pilotInstance.errors.rejectValue("version", "default.optimistic.locking.failure",
[message(code: 'pilot.label', default: 'Pilot')] as Object[],
"Another user has updated this Pilot while you were editing")
render(view: "edit", model: [pilotInstance: pilotInstance])
return
}
}
pilotInstance.properties = params
if (!pilotInstance.save(flush: true)) {
render(view: "edit", model: [pilotInstance: pilotInstance])
return
}
flash.message = message(code: 'default.updated.message', args: [message(code: 'pilot.label', default: 'Pilot'), pilotInstance.id])
redirect(action: "show", id: pilotInstance.id)
}
def delete(Long id) {
def pilotInstance = Pilot.get(id)
if (!pilotInstance) {
flash.message = message(code: 'default.not.found.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
redirect(action: "list")
return
}
try {
pilotInstance.delete(flush: true)
flash.message = message(code: 'default.deleted.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
redirect(action: "list")
}
catch (DataIntegrityViolationException e) {
flash.message = message(code: 'default.not.deleted.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
redirect(action: "show", id: id)
}
}
}

Found the solution to this problem,
def list(Integer max) {
params.max = Math.min(max ?: 10, 100)
[pilotInstanceList: Pilot.list(params), pilotInstanceTotal: Pilot.count()]
}
All you need to do is remove:
Math.min(max ?: 10, 100) in the controller,
So your code should look like this
def list(Integer max) {
params.max
[pilotInstanceList: Pilot.list(params), pilotInstanceTotal: Pilot.count()]
}
Hope this helps you in future if any of you are facing the same problem.
Kam rabwa
PilotController.list(..) returns 10 Entries if no max is given, but you don't set the max, anything else cannot happen.
And You commented pagination out, so there is no way to get the follwing entries.

I had to import the grails.util.GrailsNameUtils library to display the name in natural format.
I am new to grails I am trying to pass an object Id to a form. I have domains called Beer and recipe. Beer hasMany recipes and recipe belongsTo beer. I want to create a link to a new recipe from the beer show page passing the beer id in the url in order to create the association. Right now I have been trying to use this link <g:link controller="recpie" action="create" params="[beerid: selectedBeer.id]">Create Recipe</g:link> and retrieve it in the form as a hidden field to submit with the recipe form using <g:field type="text" name="beer.id" value="${beer}"/>.(I know that the hidden property is not set). What am I doing wrong? Also is there a better way to create this association?

beer - show.gsp
<g:link controller="recipe" action="create" resource="recipe" params="[beerid: beer.id]">Create Recipe</g:link>
recpie - create.gsp
<g:hiddenField name="beer.id" value="${params.beerid}"/>
I have been struggling with trying to create/save multiple instances at once in Grails, now I am almost there with the following code but when I hit save an empty row of options is created, can anyone help me with this
please see these two questions to see what I want to achieve

The reason that you are getting an empty row of options is because you are leaving a textfield with name option[counter] blank. This empty value is passed as a parameter to the controller action and it creates a new row with these blank values.
You should remove any blank options before calling
multipleChoiceQuestionInstance.properties = params
You can use something like this :
def emptyOptions = params.options.findAll{!it.answerOption}
params.options.removeAll(emptyOptions)
I have this DomainClass:
package cm
class XXX{
String city
String website
static constraints = {
city(nullable: true)
website(nullable: true)
}
static mapping = {
id column:'xxx_id'
city column: 'xxx_city'
website column: 'xxx_website'
table "xxx_XXX"
version false
}
}
The Controller:
class ConferenceController {
static allowedMethods = [save: "POST", update: "POST", delete: "POST"]
def index = {
redirect(action: "list", params: params)
}
def list = {
params.max = Math.min(params.max ? params.int('max') : 10, 100)
[XXXInstanceList: XXX.list(params), XXXInstanceTotal: XXX.count()]
}
def save = {
def XXXInstance= new XXX(params)
if (!XXXInstance.save(flush: true)) {
render view: 'add', model: [XXXInstance: XXXInstance]
return
}
//flash.message = "${message(code: 'default.created.message', args: [message(code: 'person.label', default: 'Person'), personInstance.id])}"
redirect(uri:"/index.gsp")
}
}
and my add.gsp page:
<head>
<title> xXXx</title>
<meta name="layout" content="main2" />
</head>
...
<g:form controller="XXX" action="save">
<g:hasErrors bean="${XXXInstance}">
<div class="errors">
<g:renderErrors bean="${XXXInstance}" as="list" />
</div>
</g:hasErrors>
year
<g:textField name="year" /><br>
website
<g:textField name="website" /><br>
<g:submitButton name="save2" value="Save" />
</g:form></div>
</div>
...
</body>
With this current code, everything works fine, but when a contraint is failed, it is showns the corresponding error but the written values are gone.. I cant figure this out - i'v tried a lot of things, but im sure the solution is as easy as my question -.- Please help.
I think you should check the *.properties file in YOUR_PROJECT\grails-app\i18n folder. They have the definition for translation. Investigate it for a time and refer to the document if need, you will understand how Grails perform translation.
And uncomment the following line in your controller:
//flash.message = "${message(code: 'default.created.message', args: [message(code: 'person.label', default: 'Person'), personInstance.id])}"
I have the create inside the table/list that Grails provides.
Here is a pictures of what I have
As you can see, I create everything on the first row of my table, and then from the 2nd row and on is the actual list.
In the last column of the 2nd row, you can see I have the UPDATE button and a delete button.
The delete button seems to be working fine, but I am having problems with the UPDATE button.
Here is the code for that last column
<g:form>
<g:hiddenField name="id" value="${densityInstance?.id}" />
<g:actionSubmit class="editar" action="update" value="${message(code: 'default.button.editar.label', default: ' ')}" />
<g:actionSubmit class="eliminar" action="delete" value="${message(code: 'default.button.eliminar.label', default: ' ')}" onclick="return confirm('${message(code: 'default.button.delete.confirm.message', default: 'Are you sure you want to delete?')}');" />
</g:form>
And here is what I have for the delete and update in the controller
def delete = {
def densityInstance = Density.get(params.id)
if (densityInstance) {
try {
densityInstance.delete(flush: true)
flash.message = "${message(code: 'default.deleted.message', args: [message(code: 'density.label', default: 'Density'), params.id])}"
redirect(action: "list")
}
catch (org.springframework.dao.DataIntegrityViolationException e) {
flash.message = "${message(code: 'default.not.deleted.message', args: [message(code: 'density.label', default: 'Density'), params.id])}"
redirect(action: "show", id: params.id)
}
}
else {
flash.message = "${message(code: 'default.not.found.message', args: [message(code: 'density.label', default: 'Density'), params.id])}"
redirect(action: "list")
}
}
The DELETE seems to be working fine, and here is the UPDATE, (maybe is the SAVE def that I need to edit, I'm not so sure and that's why I'm asking.
Here is the UPDATE:
def update = {
def densityInstance = Density.get(params.id)
if (densityInstance) {
if (params.version) {
def version = params.version.toLong()
if (densityInstance.version > version) {
densityInstance.errors.rejectValue("version", "default.optimistic.locking.failure", [message(code: 'density.label', default: 'Density')] as Object[], "Another user has updated this Density while you were editing")
render(view: "list", model: [densityInstance: densityInstance])
return
}
}
densityInstance.properties = params
if (!densityInstance.hasErrors() && densityInstance.save(flush: true)) {
flash.message = "${message(code: 'default.updated.message', args: [message(code: 'density.label', default: 'Density'), densityInstance.id])}"
redirect(action: "list", id: densityInstance.id)
}
else {
render(view: "list", model: [densityInstance: densityInstance])
}
}
else {
flash.message = "${message(code: 'default.not.found.message', args: [message(code: 'density.label', default: 'Density'), params.id])}"
redirect(action: "list")
}
}
Thanks in advance!
The g:form you have is only on the final table column, with one hidden form parameter, the id. Delete works, since all it needs is an id. The update requires the rest of the form entries. The editable fields each have a form entry, but they are not enclosed in that g:form, so their data isn't submitted with the form.
You need to make the g:form enclose all the columns of the table row. For example:
<g:form>
<tr>
<td>${densityInstance?.id}<g:hiddenField name="id" value="${densityInstance?.id}" /></td>
<td><g:textField name="commodity" value="${...}"/></td>
...
<td>
<g:actionSubmit class="editar" action="update" value="${message(code: 'default.button.editar.label', default: ' ')}" />
<g:actionSubmit class="eliminar" action="delete" value="${message(code: 'default.button.eliminar.label', default: ' ')}" onclick="return confirm('${message(code: 'default.button.delete.confirm.message', default: 'Are you sure you want to delete?')}');" />
</td>
</tr>
</g:form>
