grails - Search records bases on latest record in a hasmany relationship -


I have two domains 

  class domains {string name date date sorted date last update Fixed Static = ['Email'] is static Haimyanya = [domain BS: domain B] public string getEmail () {DomainB.mostRecentRecord (this) .get () ?. Email}}   
 and  
  class domainb {String Email Date Date Created Date Last Updated Stable Stability = [Domain A: DomainA] Static nameQueries = {Most Recently Recorded {domainA - & gt; Eq 'domainA', domainA order ('dateCreated', 'desc') maxResults (1)}}}   
  I need to get a list of all domains whose name starts with The "M" and latest domain B's records contain Gmail in their email properties.   
 I tried  createCriteria  and  hql  but did not get the desired result, maybe I'm doing something wrong.  
 The following is my current code  
  list & lt; Domain A & gt; listA = DomainA.findAllByNameIlike ("M%") list & lt; DomainB & gt; ListB = [] list a.each {entity -> DomainB domainB = DomainB.mostRecentRecord (entity) .get () if (domainB & amp; amp; amp; domainB.Mail.contains ('gmail')) {{{{{{}}}}  > 
 but it does not allow pagination and sorting on the page.  
 Do anyone have an idea of ​​getting a list of all domains whose name starts with "M" and         
 
 
 Since you seek the most recent email You are required to see the maximum date on your second domain. You can write it using HQL and use Executex to pass your paging parameter. Just make an index on your  dateCreated .  
  FirstDomain.executeQuery ("FirstDomain fd, choose from seconddomain sd, where \ sd.firstDomain.id = fd.id and fd.name like: name and sd.email like: email \ and Sd.dateCreated = (Second Donan SD2 to sd2.firstDomain.id = fd.id)), [Max: '% gmail%', name: 'm%'], maximum max (select sd2.dateCreated), [max. : 10, Offset: 0])   
: Just press the first domain controller  
  def fd // Most recent email Gmail FD = new firstname (name Is: MTAST ") fd.addToSecondDomain (email: 'yahoo.com')) fd.addToSecondDomain (New Second Domain (email: 'gmail.com')) fd.save (flush: true) // Fd.addToSecondDomain (new seconds domain (email: 'yahoo.com')) fd.addToSecondDomain (new secondsDemain (email: 'gmail.com')) .save (flush: true) // "mestst" firstdomain. First Damen FD from "FDAT" (FD) will return to SD card, where sd.firstDomain.id = fd.id and fd.name like: name and sd.email such as: email and sd.dateCreated = (second dimension SD2 Select the maximum (sd2.dateCreated) where sd2.firstDomain.id = fd.id), [email: '% gmail%', name: 'm%'])

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number".

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
