java - LazyInitialization Exception -

-

मेरे पास हाइबरनेट ऑब्जेक्ट हैं:

डेरो और आकृति।

एक डायरो मोटीफ का एक सेट है।

मैं डीबी जुर्माना से एक डीरो ऑब्जेक्ट लोड करता हूं। लेकिन जब मैं आकृति के अपने सेट का उपयोग करने की कोशिश करता हूं: 

  assertEquals (dero.getMotifRefus (), deroFromDB.getMotifRefus ());

मुझे कोई अपवाद मिलता है: 

  org.hibernate.LazyInitializationException: आलसी भूमिका को संग्रहित करने में विफल: com.dossier.Derogation.motifRefus, नहीं सत्र या सत्र org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException पर बंद किया गया था (AbstractPersistentCollection.java:358)

मैं यह कैसे हल कर?

ऐसा लगता है कि आर्टिकल के आलसी सेट से पहले डायरो को लाया जाने वाला सत्र बंद हो गया था।

यह एक स्प्रिंग संचालित वेबएप के बारे में बात करने पर, OpenSessionInViewFilter आपके लिए होगा 

 <कोड> & lt; फ़िल्टर & gt; & LT; फिल्टर-नाम & gt; OpenSessionFilter & lt; / फिल्टर-नाम & gt; & LT; फिल्टर श्रेणी & gt; org.springframework.orm.hibernate3.support.OpenSessionInViewFilter & lt; / फिल्टर श्रेणी & gt; & Lt; / फ़िल्टर & gt;

मुझे यकीन है कि किसी भी वेबपैकेज के लिए इसी तरह का समाधान उपलब्ध है।

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...
