I have problem with update foreign key in a instance of my domain class Semester. I'm new in Groovy Grails. When I create new Semester everything is ok.
Semester.groovy
class Semester {
int name
Season season
}
Season.groovy
class Season {
String name
}
SemesterController.groovy
SemesterController{
def update(){
def semester = Semester.get(params.id)
semester.name = params.semester
semester.season = params.season // Here is a problem !!
semester.save(flush: true)
redirect(uri: "/semester/index")
}
}

When I'm trying save changes I have this Exception:

Class: java.lang.IllegalStateException
Message: Cannot convert value of type [java.lang.String] to required type [com.sarna.entity.Season] for property 'season': no matching editors or conversion strategy found
What am I doing wrong ? Could you help me? Thanks
Make the following changes to the form
<g:form class="form-horizontal" role="form"
url="[resource:semester, controller: 'Semester']">
<g:hiddenField name="id" value="${semester.id}"/>
<label for="semester" class="col-sm-2 control-label">Semestr</label>
<g:textField class="form-control" name="name" value="${semester.name}" />
<g:select name="season.id" from="${com.sarna.entity.Season.list()}" optionKey="id"
optionValue="name" value="${semester?.season?.id}"/>
<g:actionSubmit class="btn btn-primary" value="Zapisz"
action="update" />
</g:form>
You can then simplify your action to:
SemesterController{
def update(Semester semester){
semester.save(flush: true)
redirect(uri: "/semester/index")
}
}

I have a Recipe, Ingredient and RecipeIngredient domains as below:
class Ingredient {
String title
}
class Recipe {
String title
String description
static hasMany = [ingredients: RecipeIngredient]
}
class RecipeIngredient {
Ingredient ingredient
static belongsTo = [recipe: Recipe]
Measure measure
Double amount
}
In my recipe/Create.gsp page when I want to create a new recipe, I want to add its ingredients one by one and addto recipe instance and save them all together.
<g:form controller="recipe" action="save" method="POST">
**/* HERE I WANT TO BE ABLE TO ADD ALL INGREDIENTS ONE BY ONE */
<select value="${recipe_ingredient.ingredient}">
<g:each in="${allIngredients}" status="i" var="ingredient">
<option>${ingredient.title}</option>
</g:each>
</select>
<select name="recipe_ingredient.measure" value="${recipe_ingredient.measure}">
<g:each in="${enums.Measure.values()}" var="m">
<option>${m}</option>
</g:each>
</select>
<input name="recipe_ingredient.amount" placeholder="Measure" value="${recipe_ingredient.amount}" />
<g:actionSubmit value="Add" action="addIngredient" />
/* END */**
<div class="row">
<input name="title" value="${instance?.title}" placeholder="Title" />
</div>
<div class="row">
<input name="titleEng" value="${instance?.description}" placeholder="Description" />
</div>
<div class="row">
<g:submitButton name="Create" />
</div>
</g:form>
How can I achieve such thing?
The straight-forward way would be:
<g:select name="rawIngredients" value="${recipe.ingredients*.ingredient*.id}"
from="${allIngredients}" optionKey="id" optionValue="title" multiple="true"/>
Then in the controller:
def save() {
Recipe recipe // bind or create somehow, e.g. via command-object
recipe.ingredients?.clear()
Ingredient.getAll( params.list( 'rawIngredients' ) ).each{ ing ->
recipe.addToIngredients new RecipeIngredient( ingredient:ing, amount:1, ... )
}
recipe.save()
}
How obtain value of hotel in Controller ? now i have only null. The nested object are not allowed because of html 5 doesn't let to be nested.

I have following code on my view.
This HTML code is used for search in website.
This view is not strongly typed view, so I can apply use DataAnnotation through model.
What is best view to validate that, this textbox should accept only alpha numeric characters?
HTML
<form action="Search" method="post" >
<div class="col-md-8">
<input type="text" name="name" placeholder="search" class="fullwidth" onkeypress="return BlockingHtml(this,event);" />
</div>
<div class="col-md-4">
<input type="submit" title="Search" value="Search" />
</div>
</form>
Javascript
function BlockingHtml(txt) {
txt.value = txt.value.replace(/[^a-zA-Z 0-9\n\r.]+/g, '');
}
Model:-
[StringLength(100)]
[Display(Description = "Name")]
[RegularExpression("(/[^a-zA-Z 0-9\n\r.]+/g", ErrorMessage = "Enter only alphabets and numbers of Name")]
public string Name{ get; set; }
Updated:-
View:-
<form action="Search" method="post" >
<div class="col-md-8">
<input type="text" name="name" id="txt" placeholder="search" class="fullwidth" onkeypress="BlockingHtml(this);" />
</div>
<div class="col-md-4">
<input type="submit" title="Search" value="Search" />
</div>
</form>
function BlockingHtml(txt) {
txt.value = txt.value.replace(/[^a-zA-Z 0-9\n\r.]+/g, '');
}
<form action="Search" method="post" >
<div class="col-md-8">
<input type="text" name="name" placeholder="search" class="fullwidth" onblur="return BlockingHtml(this,event);" />
</div>
<div class="col-md-4">
<input type="submit" title="Search" value="Search" />
</div>
</form>
Changed event onkeypress to onblur.
how can I update the data other than form. ? I created a button but do not update my data.
<html>
<head>
<meta name="layout" content="main">
<g:set var="entityName" value="${message(code: 'product.label', default: 'product')}" />

</label>
<g:select id="id" name="id" from="${com.app.product.findAll([sort:"symbolIndeksu"])}" optionKey="id" value="${productInstance?.id}" class="many-to-one inptSearch chzn-select" />
<g:actionSubmit class="save" action="edytuj" value="Zmień" />
<g:actionSubmit class="save" action="aktualizuj" value="${message(code: 'default.button.update.label', default: 'Update')}" />
/* Button at this point should update the data */

In summary. I would like to use the update button outside of the form g: form. Previously, I had the buttons at the bottom
I am completely new in Grails, start learning grails from past couple of days. I am trying to add search feature by using searchable plugin in my demo grails application. I successfully added searchable plugins on user search where user can search other users and follow them. I am doing like this ..
grails install-plugin searchable
Domain Person.groovy --
package org.grails.twitter
class Person {
transient springSecurityService
String realName
String username
String password
boolean enabled
boolean accountExpired
boolean accountLocked
boolean passwordExpired
static hasMany = [followed:Person, status:Status]
static searchable = [only: 'realName']
static constraints = {
username blank: false, unique: true
password blank: false
}
static mapping = {
password column: '`password`'
}
Set<Authority> getAuthorities() {
PersonAuthority.findAllByPerson(this).collect { it.authority } as Set
}
def beforeInsert() {
encodePassword()
}
def beforeUpdate() {
if (isDirty('password')) {
encodePassword()
}
}
protected void encodePassword() {
password = springSecurityService.encodePassword(password)
}
}
view/searchable/index.gsp ---
<html>
<head>
<meta name="layout" content="main" />
<title>What Are You Doing?</title>
<g:javascript library="jquery" plugin="jquery" />
</head>
<body>
<h1>Search For People To Follow</h1>
<div class="searchForm">
<g:form controller="searchable">

</g:form>
</div>
<h1>What Are You Doing?</h1>
<div class="updateStatusForm">
<g:formRemote onSuccess="document.getElementById('messageArea').value='';" url="[action: 'updateStatus']" update="messageLists" name="updateStatusForm">

<g:submitButton name="Update Status" />
</g:formRemote>

<div id="messageLists">

</div>

</html>
It works fine. Now My problem starts. Now I want to add this searchable in my Post domain also where user can search post items. I am doing like this ...
Domain Post.groovy --
package groovypublish
class Post {
static hasMany = [comments:Comment]
String title
String teaser
String content
Date lastUpdated
Boolean published = false
SortedSet comments
static searchable = [only: 'title']
static constraints = {
title(nullable:false, blank:false, length:1..50)
teaser(length:0..100)
content(nullable:false, blank:false)
lastUpdated(nullable:true)
published(nullable:false)
}
}
and here is form view
view/post/list.gsp --
------ some code -----
<g:form controller="searchable" class="navbar-search pull-left">
<g:textField name="q" value="" class="search-query" placeholder="Search Posts"/>
</g:form>
------ some code ------
Now when I try to search post by post title then it showing error. It overrides searchable action. How to solve this problem ?
You can implement your own search method using searchable, call a controller function from your search form and perform search in that:
Let say you have two search forms:
<g:form controller="postsController" action="postAction" class="navbar-search pull-left">
<g:textField name="q" value="" class="search-query" placeholder="Search Posts"/>
</g:form>
and
<g:form controller="searchable">
<g:textField name="q" value=""/>
</g:form>
then in the PostCOntroller you can have postAction method to perform search:
def postAction (Integer max) {
params.max = Math.min(params.max ? params.int('max') : 10, 100)
params.sort = "id"
params.order = "desc"
if(params?.q){
def result = Post .search(params.q , order:"desc" )
return [searchResults: result.results, searchResultsCount: result.total, popup : params.popup?.toBoolean()]
}else{
[searchResults: Post .list(params), searchResultsCount: Post .count(), popup : params.popup?.toBoolean()]
}
and same you can have a different function for another search, if you use remote form then you need to have two different div's on the search page, and you can render the result page out there.
let say you have:
<g:formRemote name="postSearchForm" update="postSearchResultsDiv" url="[controller: 'post', action:'postAction' , params: [popup: false]]">
<label for="searchText">Search Post:</label>
<input name="q" type="text" id="searchText" class="input-medium search-query"/>
<input id="searchButton" type="submit" class="btn-info" value="Search"/>
</g:formRemote>
<div id="postSearchResultsDiv">--Your search result for the form will display here--</div>
This remote form will call postAction method in your controller, you can have postAction.gsp page on the controller's view folder and print the result out there.
and on your search page, postSearchResultsDiv will have the search result(postAction GSP page output)
I solved my own problem...
I have done like this ..
PostController ---
import org.compass.core.engine.SearchEngineQueryParseException
class PostController
{
def searchableService
def searchpost = {
if (!params.q?.trim()) {
return [:]
}
try {
return [searchResult: searchableService.search(params.q, params)]
} catch (SearchEngineQueryParseException ex) {
return [parseException: true]
}
render(view:'searchpost')
}
.......
}
Search form ---
<g:form controller="post" action="searchpost" class="navbar-search pull-left">
<g:textField name="q" value="" class="search-query" placeholder="Search Posts"/>
</g:form>
searchpost.gsp //for showing result
<html>
<head>
<r:require modules="bootstrap"/>
<meta name="layout" content="main"/>
</head>
<body>
<g:render template="/layouts/header" />
<div class="well">
<g:each var="post" in="${searchResult?.results}">
<div>
<h2>${post.title}</h2>
<p>${post.teaser}</p>
<p>Last Updated: ${post.lastUpdated}</p>
<g:link controller="post" action="view" id="${post.id}" class="btn btn-success">
View this post
</g:link>
<g:if test="${post.author == currentLoggedInUser }">
<g:link controller="post" action="edit" id="${post.id}" class="btn btn-danger">
Edit this post
</g:link>
<g:actionSubmit action="delete" value="${message(code: 'default.button.delete.label', default: 'Delete')}" onclick="return confirm('${message(code: 'default.button.delete.confirm.message', default: 'Are you sure?')}');" class="btn btn-inverse" />
</g:if>
<g:form>
<g:hiddenField name="id" value="${post?.id}" />
</g:form>
</div>
</g:each>
</div>
</body>
</html>
And it works :)
