java - JSF add a commandLink tag or outputText tag depand on a boolean flag -

-

मेरे पास userBean ऑब्जेक्ट के साथ name , id है , बूलीयन कनेक्ट है ।

मैंने JSF का उपयोग करके लॉगिन पृष्ठ बनाया है अगर एक लॉगिन सफलतापूर्वक, अगले पृष्ठ सभी उपयोगकर्ताओं (नाम, आईडी) की एक तालिका है

मुझे जो चाहिए वह उपयोगकर्ता के कॉलम पर होता है जो उसकी आईडी में लॉग इन किया गया एक h में दिखाया जाएगा : कमांडलिंक , और शेष यूजर आईडी एक h: आउटपुट टेक्स्ट टैग में होगा।

जब उपयोगकर्ता ने अपने isConnected में लॉग इन किया हो > ध्वज ( बूलियन ) true है और अन्य सभी उपयोगकर्ता झूठे हैं।

क्या कोई भिन्न सम्मिलित करने का कोई तरीका है टैग मेरे जैसे एक निश्चित ध्वज पर निंदा? मेरी managerBean पर एक विधि कॉल करने की तरह कुछ ऐसा है जो पेज पर उपयोगकर्ता फ्लैग init पर निर्भर करता है।

< Div code = "post-text" itemprop = "text">

सबसे आसान तरीका संभवतः rendered विशेषता को outputText और commandLink < / Code> tags।

उदाहरण के लिए, निम्न की तरह कुछ: 

  ... & lt; h: डेटाटेबल मान = "# {MyBean.users}" var = "उपयोगकर्ता" & gt; ... & lt; h: स्तंभ & gt; & Lt; h: कमांड लिंक्ड गाया गया = # {user.connected} value = "# {user.id}" / & gt; & Lt; h: आउटपुट टेक्स्ट प्रस्तुत = # {! User.connected} value = "# {user.id}" / & gt; & Lt; / h: स्तंभ & gt; ... & lt; / h: डेटाटेबल & gt; ...

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
