File upload with Rails 4 and Bootstrap -

-

It's probably a simple (?) Fixed, but I can not seem to find it. I am working on a rail site and almost finished I have a form in which the file upload field is included (using a paperclip) to optimize, I am following the following.

I have this setup, but when I select a file, the file name is not being displayed. Here's the relevant bit of code from my site: 

    
 CSS (currently) matches what's linked in the above linked guide. I think I need to convert : image  to  f.text_field  to something else, but I can not understand it. Maybe it's a security thing.   
 
 
 No problem, I thought there was some underlying method for it. It seems that I had to add JS

सी / सी ++ में एक सरणी के लिए एक विशिष्ट घोषणा है: प्रकार का नाम [तत्व]; जहां एक प्रकार वैध है (जैसे कि इंट, फ्लोट ...), नाम एक मान्य पहचानकर्ता और तत्व फ़ील्ड है (जो हमेशा चौकोर ब्रैकेट्स [] में संलग्न होता है), सरणी की लंबाई को निर्दिष्ट करता है तत्वों की संख्या के संदर्भ में। इसलिए मैं एक सरणी की घोषणा करता हूँ जिसमें 2 तत्व हैं int a [2]; एक [3] = 4; क्यों यह अपवाद नहीं फेंकते? सीमा से बाहर की जाँच कुछ ऐसा है जो आप संभवतः जावा जैसे कुछ उच्च स्तर की भाषा से उपयोग किया जाता है। हालांकि सी / सी ++ में यह डिफ़ॉल्ट रूप से नहीं किया जाता है। यह आपको सरणी की सीमाओं की जांच करने के लिए एक छोटा प्रदर्शन हिट देता है और इसलिए सी तर्क यह है कि आप इसे स्वयं मैन्युअल रूप से कर सकते हैं, जब तक आप इसे सर्वश्रेष्ठ संभव प्रदर्शन की पेशकश कर सकते हैं। सी + + एसटीएल कंटेनर जैसे वेक्टर आमतौर पर एक पर () ऑपरेशन को बाध्य जांच करने के लिए समर्थन देता है और चूंकि आप [] अधिभार लोड कर सकते हैं - आप सरणी के लिए बाउंड-चेक सक्षम कर सकते हैं -स्टाइल एक्सेस। यदि सरणी एक कच्चे पॉइंटर ह...

java - Projects which are accessed via multiple (different) IDEs: Ant or Maven? -

-
Is it true that Maven's real advantage is that its project structure is clearly defined and therefore it should be opened. Could any IDE support Maven? We develop a team of 5 people and we use three different IDEs (Intellees, Eclipse, Netbeans). I know that I can not open Eclipse an ant project in Netbeans but with Maven it is possible. Is it really reason enough to use Maven? Ante is the creation tool when the functionality of Maven accumulates: Construction equipment (included ant), Not only jar / war / project etc The order environment (such as starting a jetty and deploying its artifact) Unit Testing Li> Integration test Deployment (incrementing, incrementing versions, deploying artifacts etc.) More (see t for plugins on i-ne) Maven uses the lifestyle to achieve this goal. You can trigger some functionality at some points of the lifecycle. For example, the unit test should work fine after compiling, whereas integration testing ...
