  • Map problem when passing it as model to view in grails

    - by xain
    Hi, In a controller, I have populated a map that has a string as key and a list as value; in the gsp, I try to show them like this: <g:each in="${sector}" var="entry" > <br/>${entry.key}<br/> <g:each in="${entry.value}" var="item" > ${item.name}<br/> </g:each> </g:each> The problem is that item is considered as string, so I get the exception Error 500: Error evaluating expression [item.name] on line [11]: groovy.lang.MissingPropertyException: No such property: nombre for class: java.lang.String Any hints on how to fix it other than doing the find for the item explicitly in the gsp ?

  • Grails Shiro plugin : confirming my understanding

    - by bsreekanth
    I'm bit vague about how to start using the shiro plugin, after reading few documents. I decided against Nimble, as it comes with few tables and UI plugins. I setup shiro plugin with wildcard realm, with my own tables. I may use permission based (rather tan role based) access control as it scales well. Now, the steps for it. assign the permission string to the subject, and save it in the db check the permission through isPermitted, hasPermission (or relevant tags in GSP). Now, 1. when to use the accesscontrol through filter? 2. is there a closure injected into the controller where I can define the permission for the actions in it? 3. How do I create a typical access control scenario like only the creator of (something, a post etc) can delete it? thanks a lot.. Babu.

  • rendering JSON in GRAILS with part of the attributes of an object

    - by bsreekanth
    Hello, I am trying to build JSON from two fields. Say, I have a list of object(party), and I only need to pass 2 items as JSON pair. def list = getMyList() //it contains 2 party objects partyTo = array { for (i in list) { x partyId: i.id y partyName: i.toString() } } The JSON string is {"partyTo":[ {"partyId":12}, {"partyName":"Ar"}, {"partyId":9}, {"partyName":"Sr"} ] } when I extract it at the client, it is treated as 4 objects. I wanted as 2 objects, with the below format. {"partyTo":[ {"partyId":12 , "partyName":"Ar"}, {"partyId":9 , "partyName":"Sr"} ] } I'm getting 4 objects, probably because I use an array to build JSON. I'm new to groovy and JSON, so not sure about the right syntax combinations. Any help highly appreciated. thanks.

    - by Visionary Software Solutions
    Neither a Tomcat nor SSI pro, I'm trying to use a provided template that relies on them heavily for look and feel. The Tomcat page says that SSI is disabled by default. It's installation instructions talk about renaming a Catalina.jar file, which I cannot find in $GRAILS_HOME. How can I configure the bundled Tomcat instance for SSI?

  • Grails / GORM, read-only cache and transient fields

    - by Stephen Swensen
    Suppose I have the following Domain object mapping to a legacy table, utilizing read-only second-level cache, and having a transient field: class DomainObject { static def transients = ['userId'] Long id Long userId static mapping = { cache usage: 'read-only' table 'SOME_TABLE' } } I have a problem, references to DomainObject instances seem to be shared due to the caching, and thus transient fields are writing over each other. For example, def r1 = DomainObject.get(1) r1.userId = 22 def r2 = DomainObject.get(1) r2.userId = 34 assert r1.userId == 34 That is, r1 and r2 are references to the same instance. This is undesirable, I would like to cache the table data without sharing references. Any ideas?

  • Grails multiple databases

    - by srinath
    Hi, how can we write queries on 2 databases . I installed datasources plugin and domain classes are : class Organization { long id long company_id String name static mapping = { version false table 'organization_' id column : 'organizationId' company_id column : 'companyId' name column : 'name' } } class Assoc { Integer id Integer association_id Integer organization_id static mapping = { version false table 'assoc' id column : 'ASSOC_ID' association_id column : 'ASSOCIATION_ID' organization_id column : 'ORGANIZATION_ID' } } this is working : def org = Organization.list() def assoc = Assoc.list() and this is not working : def query = Organization.executeQuery("SELECT o.name as name, o.id FROM Organization o WHERE o.id IN (SELECT a.organization_id FROM Assoc a )") error : org.hibernate.hql.ast.QuerySyntaxException: Assoc is not mapped [SELECT o.name as name, o.id FROM org.com.domain.Organization o WHERE o.id IN (SELECT a.organization_id FROM AssocOrg a )] How can we connect with 2 databases using single query ? thanks in advance .

  • Grails- Unique constraint

    - by WaZ
    How can I basically carry out a unique constraint on a string data-type field. class User{ String username String Email static hasMany = [roles:Roles] static constraints = { Email(email:true) username(unique:true) } Is there any simple way to implement username(unique:true) or I will have to manually check the database by the in-built methods like .findByNameLike. My need is that username should be unique and should be case insensitive

  • Grails efficient hasMany-Relationship in View

    - by Jan
    Hi folks, I'm saving contacts (email, mobile phone, ICQ, AIM etc.) for people like this: class Person { static hasMany = { contacts: Contact } } class Contact { String code ContactType type } class ContactType { String name } In my view, I've written some Templates for displaying each contact with a select-box for the contact-type and a textfield for the code, spiced up with some JavaScript for adding and deleting. My question is: Is there an easy and elegant way to update the data similar to personInstance.properties = params or do I have to read out all the fields, deleting removed, updating changed and adding new ones?

  • Grails Date Property Editor

    - by Jan
    Hey folks, i'm using the jQuery UI datepicker instead of the <g:datePicker>, which is changing the selected date in a textbox. Now I want to save this neatly back into my database, and came across custom property editors. click me hard to see the topic on StackOverflow However, adding this custom PropertyEditor didn't change anything, dates are still displayed like '2010-01-01 00:00:00.0' and if I try to save a date it crashes with Cannot cast object '05.05.2010' with class 'java.lang.String' to class 'java.util.Date'. Is there any additional magic needed, like a special naming of the textbox or something like that? Thanks for your help, Jan

  • Grails/Groovy taglib handling parsing dynamically inserted tags.

    - by Dan Guy
    Is there a way to have a custom taglib operate on data loaded in a .gsp file such that it picks up any tags embedded in the data stored in the database. For instance, let's say I'm doing: <g:each in="${activities}"> <li>${it.payload}</li> </g:each> And inside the payload, which is coming from the database, is text like "Person a did event <company:event id="15124124">Event Description</company:event>" Can you have a taglib that handles company:event tags on the fly?

  • Grails withCriteria testing

    - by Steve Wall
    Hello, I'd like to test a "withCriteria" closure and am not sure how to go about it. I see how to mock out the withCriteria call, but not test the code within the closure. When running the test that executes the "withCriteria", I keep getting a MissingMethodException, even though the code runs fine under the normal flow of execution. Any ideas? Thanks! Steve

  • Groovy on Grails: GORM and BitSets?

    - by Visionary Software Solutions
    I don't see anything in the official documentation about unsupported persistence data types, so I'm working under the assumption that types available in the Groovy language should be handled. However, for the following domain class: class DocGroupPermissions { Workgroup workgroup; Document document; BitSet permissions = new BitSet(2) public DocGroupPermissions() {} void setPermissions(boolean canRead, boolean canWrite){ setReadPermissions(canRead) setWritePermissions(canWrite) } BitSet getPermissions() { return permissions } void setReadPermissions(boolean canRead) { permissions.set(0,canRead) } void setWritePermissions(boolean canWrite) { permissions.set(1,canWrite) } boolean getReadPermissions() { return permissions.get(0) } boolean getWritePermissions() { return permissions.get(1) } static belongsTo = [workgroup:Workgroup, document:Document] static constraints = { workgroup(nullable:false, blank:false) document(nullable:false, blank:false) } } I'm getting: 2009-11-15 16:46:12,298 [main] ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageSource': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.hibernate.MappingException: An association from the table doc_group_permissions refers to an unmapped class: java.util.BitSet Has anyone run into this before?

  • Getting the OpenID URL from a Grails Controller/Service

    - by firnnauriel
    I'm using acegi 0.5.2 and enabled OpenID support. I would like to know how to accesss the URL (or username) returned by a provider (i.e. Google, Yahoo!). I can't find any docs about that so I traced the code of acegi and found this in GrailsOpenIdAuthenticationProvider: OpenIDAuthenticationToken response = (OpenIDAuthenticationToken) authentication OpenIDAuthenticationStatus status = response.status // handle the various possibilites if (status == OpenIDAuthenticationStatus.SUCCESS) { // Lookup user details UserDetails userDetails = _userDetailsService.loadUserByUsername(response.identityUrl) return new GrailsOpenIdAuthenticationToken(userDetails, response.status, response.identityUrl) } it seems that the response.identityUrl contains what i need. How can get it from a controller's (or service's) space? Thanks.

  • Grails pattern to reuse template on error

    - by bsreekanth
    Hello, I have a gsp template, where the data for create view is passed through the controller. def create = { def bookInstance = new Book() bookInstance .properties = params def map = getDefaultValues() render(template: "create", model: [bookInstance : bookInstance , title: map.title, somelist: somelist ....]) the gsp template <g:select optionKey="id" from="${somelist}" name="somelist.id" value="${bookInstance ?.somelist?.id}" noSelection="['null': '']"></g:select> now, in the save method, if there is an error, it returns currently populated and validated instance (default scaffold implementation) render(template: "create", model: [bookInstance : bookInstance ]) But the fields in the gsp (error page rendered from save action) is empty. I could see the reason as it looks the value in "${somelist}" , but it is not used in save method. Do i just need to check for null in the gsp and use whichever map is available, or any better method (passing all the map in the save method is not an option) .. thanks in advance..
