Ruby/Rails - Using a symbol or string to define model -

-

मेरे पास निम्न कोड है: 

  यदि पैरामीटर [: reviewable_type] == 'प्रस्ताव 'समीक्षा योग्य = ऑफर.फंड (पाराम [: समीक्षा योग्य_आईडी]) एल्सफ पैरामीटर [: समीक्षा योग्य_प्रकार] ==' अनुरोध 'समीक्षा योग्य = अनुरोध। खोज (पैरामीटर [: समीक्षा योग्य_आईडी])

क्या मैं params [: reviewable_type] जैसे कुछ करने से इसे सरल करें। ढूँढें (पैरामीटर [: reviewable_id]) , अनिवार्य रूप से मॉडल के नाम के रूप में परम में निहित स्ट्रिंग का उपयोग?

आप बाद में हो।

हालांकि, आपको वास्तव में सिर्फ आँख बंद करके उपयोगकर्ताओं को मनमानी के उदाहरणों को इन्स्तांत करने की अनुमति नहीं देना चाहिए कक्षाएं। आपको हमेशा यह देखने के लिए जांचना चाहिए कि क्या आने वाले परम में सफेद उम्मीदवारों में से कोई एक श्वेत-सूची है: 

  यदि% w (प्रस्ताव अनुरोध)। शामिल करें? (पैराम [[reviewable_type]) समीक्षा योग्य = Params [: reviewable_type] .constantize.find (params [: reviewable_id]) समाप्ति

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
