python - MongoDB search for each dict in list in collection -

-

I have archive where list has dicts < / Code> and I want to find if a particular word has two specific key: value .

For example, I want to find find_one where my name is a word which includes a specific first and last name: 

  {"name "," "", "First name": "alias", "first name": "bob", "last name": "jones", "age": "34", "gender": "m"}, "Last name": "56", "gender": "F"}, {"first name": "Bob", "last name" is a record with "Bombay's Smith" or not To see that "Smith", "age": "19", "gender": "m"},]}   
 and last name, I am:  
  ago = 'Bob' final = 'Smith' nameExists = db.user.find_one ({'$ and': [{'names.first name': First, '   
 
  
 Post-text "itemprop =" text "> 
 Although it is mentioned that in reality there is no operator required, in both ways this is not the query that you want. Consider the following:  
  db.user.find_one ({'names.firstName': 'alice', 'names.lastName': 'jones'})   
 It actually  does  match the given record because "Jones" There are two elements of "first name" equal to equal "aliis" and "last name" But surely the problem here is simple that there is no real element in the array, in which there is a sub-document for those two values.  
 To match where the "both" criteria are given in an array element, you have to use the operator. This query condition is applied to the "element" of the array.  
  db.user.find_one ({'names': {'$ elemMatch': {'firstName': 'alice', 'last name': 'Smith'}})   
 And of course if you tried "Alice" and "Jones" then it does not match because in reality no element is involved in that operation.

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
