    <pre><code>fs.writeFile('message.txt', 'Hello Node', function (err) { if (err) throw err; console.log('It\'s saved!'); }); </code></pre> <p>I have a question regarding the use of the function <code>fs.writeFile()</code> in Node, and the fact that it prints strings into a textfile. </p> <p>At the moment, I have a piece of code that prints the following into console. Instead of the console, I would like to modify the code a bit so it would print into a textfile. </p> <pre><code>var options = { host: 'www.google.com', path: '/' }; http.get(options, function(response) { console.log("Status Code: " + response.statusCode); for(var item in response.headers) { console.log(item + ": " + response.headers[item]); } </code></pre> <p>I would like to replace <code>console.log</code> with <code>fs.writeFile</code>, however, the <code>Hello Node</code> part of the input in <code>fs.writeFile()</code> is a string. Thus, I am stuck on this part. </p> <p>The documentation for fs.writeFile() for Node.js is here: <a href="http://nodejs.org/api/fs.html" rel="nofollow">http://nodejs.org/api/fs.html</a> </p> <p>As explained in the documentation, this is how the fs.writeFile function works <code>fs.writeFile(filename, data, [encoding], [callback])</code>. My question is in regards to the <code>data</code> input. </p> <p>I am fairly new to Node.js, therefore I would like to get some feedback on this, and hopefully work the solution out myself with some pointers. </p> <p>EDIT 1: Do I use String() which then turns my function into a string? I don't think this is right, but it could be a possibility.</p>

    1. CO`item + ": " + response.headers[item]` is a string as well? Why do you ask for `String()` turning a function into a string, do you want to print a function?

    2. COAt the moment, console.log prints out the output. I would like to ask how I could have this output be printed into a textfile using fs.writeFile. To my knowledge, fs.writeFile prints strings (as shown in "Hello Node!"). I would like to know a work-around for that - that is my question.

    3. COWhy doesn't this work: `fs.writeFile('log.txt', "Status Code: " + response.statusCode)`?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
