问题 I am trying to create horizontal forms with simple-form and bootstrap. I have already installed bootstrap using "rails generate simple_form:install". This is what i have in html.erb <%= simple_form_for(@company, :html => { :class => "form-horizontal" }) do |f| %> <div class="form-group"> <label class="col-md-4 control-label"></label> <div class="col-md-4"> <%= f.input :name %> </div> </div> But the form still appears vertically. 回答1: simple_form is a really great gem for generating bootstrap

My F# settings seem to imply tabs are converted to 4 spaces..."insert spaces = 4" v16.8.3 very odd (actually this is a new install on a fresh machine not an upgrade, that may be relevant....I may have done something on my normal machine many moons ago, that Ive now forgotten) 回答1: I think this is the Adaptive Formatting behavior in Visual Studio: To turn off this behavior, please go to Tools > Options, and then Text Editor

问题 How can I tell the Python MySQL connector which SSL/TLS protocol to use? Either specific (e.g. TLS1.2) or minimum. How can I check which protocol is used on an established connection? I've got an app that uses mysql-connector-python (8.0.18). I connect something like this: cnx = mysql.connector.connect(user='x', password='y', host='localhost', database='xyz') Usually this gives me no trouble, but recently on a web hosting providers server it stopped working. The error I'm now getting is along

问题 We have a scan that aborts on the code below, with the exception: org.sonar.java.se.ExplodedGraphWalker$MaximumStepsReachedException: reached limit of 16000 steps for method getServiceProviders#151 in class ServiceProviderService We looked at rules S2259 and S2583 and would like to keep notifications about null pointers. This happens in both "regular" and debug (-X) mode, so it's not issue 1406. In our case it really seems to be related to try/catch. (See sample method below.) Could it be a

问题 It appears that the pandas to_csv function only allows single character delimiters/separators. Is there some way to allow for a string of characters to be used like, "::" or "%%" instead? I tried: df.to_csv(local_file, sep = '::', header=None, index=False) and getting: TypeError: "delimiter" must be a 1-character string 回答1: Use numpy-savetxt Ex: np.savetxt(file.csv, np.char.decode(chunk_data.values.astype(np.bytes_), 'UTF-8'), delimiter='~|', fmt='%s',encoding=None) np.savetxt(file.dat,

问题 I'm trying to generate a UI element that is dynamic based on how the user wishes to provide their input. I'm using the Shiny Dashboard for simplicity but I have encountered an issue with the sidebarMenu. Previously when I was placing static UI elements directly into the sidebarMenu, I had no issue, however when trying to place dynamic UI elements into the sidebarMenu I have problems. I'm using R 3.3.2 and Shiny 1.0.0 and Dashboard 0.5.3. The specific problem I have is that when the program
