The solution was to change the `for` attribute to `htmlFor`

    &lt;label htmlFor={this.props.inputId} className=&quot;input-label&quot;&gt;{this.props.label}&lt;/label&gt;

This is a part of the React library itself which apparently handles `for` differently just like it does `class` (it uses `className`) and not an issue with the definitely typed type definitions.

I have 3 environment specific `appsettings` files in my .Net core application

[![enter image description here][1]][1]

in `project.json` I have setup `publishOptions` like this. ( based on suggestion [here][2])

    &quot;publishOptions&quot;: {
        &quot;include&quot;: [
          &quot;wwwroot&quot;,      
          &quot;appsettings.development.json&quot;,
          &quot;appsettings.staging.json&quot;,
          &quot;appsettings.production.json&quot;,
          &quot;web.config&quot;
        ]
      },

I have 3 corresponding startup classes that uses appropriate `appsettings` based on environment

    var builder = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile($&quot;appsettings.{env.EnvironmentName}.json&quot;, optional: false, reloadOnChange: true);

However when I publish the application then all 3 appsettings files end up in all environments. How do I publish environment specific appsetting file?

Using typescript and react with TSX files with definitely typed type definitions, I am getting the error:

I&#39;m trying to access a static image to use within an inline `backgroundImage` property within React. Unfortunately, I&#39;ve run up dry on how to do this.

Generally, I thought you just did as follows:

    import Background from &#39;../images/background_image.png&#39;;
    
    var sectionStyle = {
      width: &quot;100%&quot;,
      height: &quot;400px&quot;,
      backgroundImage: &quot;url(&quot; + { Background } + &quot;)&quot;
    };
    
    class Section extends Component {
      render() {
        return (
          &lt;section style={ sectionStyle }&gt;
          &lt;/section&gt;
        );
      }
    }

This works for `&lt;img&gt;` tags. Can someone explain the difference between the two?

Example:

`&lt;img src={ Background } /&gt;` works just fine.

Thank you!

This is an educational project, not for production. I wasn&#39;t intending to have user logins as part of this.

Can I make POST calls to Django with a CSRF token without having user logins? Can I do this without using jQuery? I&#39;m out of my depth here, and surely conflating some concepts.

For the JavaScript side, I found this [redux-csrf](https://www.npmjs.com/package/redux-csrf) package. I&#39;m not sure how to combine it with my `POST` action using Axios:

&lt;!-- language: lang-js --&gt;

    export const addJob = (title, hourly, tax) =&gt; {
      console.log(&quot;Trying to addJob: &quot;, title, hourly, tax)
      return (dispatch) =&gt; {
        dispatch(requestData(&quot;addJob&quot;));
        return axios({
          method: &#39;post&#39;,
          url: &quot;/api/jobs&quot;,
          data: {
            &quot;title&quot;: title,
            &quot;hourly_rate&quot;: hourly,
            &quot;tax_rate&quot;: tax
          },
          responseType: &#39;json&#39;
        })
          .then((response) =&gt; {
            dispatch(receiveData(response.data, &quot;addJob&quot;));
          })
          .catch((response) =&gt; {
            dispatch(receiveError(response.data, &quot;addJob&quot;));
          })
      }
    };

On the Django side, I&#39;ve read [this documentation](https://docs.djangoproject.com/en/1.10/ref/csrf/) on CSRF, and [this](https://docs.djangoproject.com/en/1.10/topics/class-based-views/intro/#decorating-class-based-views) on generally working with class based views.

Here is my view so far:

    class JobsHandler(View):
    
        def get(self, request):
            with open(&#39;./data/jobs.json&#39;, &#39;r&#39;) as f:
                jobs = json.loads(f.read())
    
            return HttpResponse(json.dumps(jobs))
    
        def post(self, request):
            with open(&#39;./data/jobs.json&#39;, &#39;r&#39;) as f:
                jobs = json.loads(f.read())
    
            new_job = request.to_dict()
            id = new_job[&#39;title&#39;]
            jobs[id] = new_job
    
            with open(&#39;./data/jobs.json&#39;, &#39;w&#39;) as f:
                f.write(json.dumps(jobs, indent=4, separators=(&#39;,&#39;, &#39;: &#39;)))
    
            return HttpResponse(json.dumps(jobs[id]))


I tried using the [`csrf_exempt`](https://docs.djangoproject.com/en/1.10/ref/csrf/#django.views.decorators.csrf.csrf_exempt) decorator just to not have to worry about this for now, but that doesn&#39;t seem to be how that works.

I&#39;ve added `{% csrf_token %}` to my template.

This is my `getCookie` method (stolen from Django docs):

    function getCookie(name) {
        var cookieValue = null;
        if (document.cookie &amp;&amp; document.cookie !== &#39;&#39;) {
            var cookies = document.cookie.split(&#39;;&#39;);
            for (var i = 0; i &lt; cookies.length; i++) {
                var cookie = cookies[i].trim();
                // Does this cookie string begin with the name we want?
                if (cookie.substring(0, name.length + 1) === (name + &#39;=&#39;)) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                    break;
                }
            }
        }
        return cookieValue;
    }


[I&#39;ve read](https://www.snip2code.com/Snippet/573695/override-axios-default-csrf-header-and-c) that I need to change the Axios CSRF info:

    var axios = require(&quot;axios&quot;);
    var axiosDefaults = require(&quot;axios/lib/defaults&quot;);
    
    axiosDefaults.xsrfCookieName = &quot;csrftoken&quot;
    axiosDefaults.xsrfHeaderName = &quot;X-CSRFToken&quot;

Where do I stick the actual token, the value I get from calling `getCookie(&#39;csrftoken&#39;)`?



CSRF with Django, React+Redux using Axios

I have a reducer, and in order to calculate the new state I need data from the action and also data from a part of the state not managed by this reducer.  Specifically, in the reducer I will show below, I need access to the `accountDetails.stateOfResidenceId` field.

**initialState.js:**

	export default {
		accountDetails: {
			stateOfResidenceId: &#39;&#39;,
			accountType: &#39;&#39;,
			accountNumber: &#39;&#39;,
			product: &#39;&#39;
		},
		forms: {
			blueprints: [
				
			]
		}
	};

**formsReducer.js:**

    import * as types from &#39;../constants/actionTypes&#39;;
    import objectAssign from &#39;object-assign&#39;;
    import initialState from &#39;./initialState&#39;;
    import formsHelper from &#39;../utils/FormsHelper&#39;;
    export default function formsReducer(state = initialState.forms, action) {
      switch (action.type) {
        case types.UPDATE_PRODUCT: {
            //I NEED accountDetails.stateOfResidenceId HERE
            console.log(state);
            const formBlueprints = formsHelper.getFormsByProductId(action.product.id);
            return objectAssign({}, state, {blueprints: formBlueprints});
        }

        default:
          return state;
      }
    }

**index.js (root reducer):**

	import { combineReducers } from &#39;redux&#39;;
	import accountDetails from &#39;./accountDetailsReducer&#39;;
	import forms from &#39;./formsReducer&#39;;

	const rootReducer = combineReducers({
		accountDetails,
		forms
	});

	export default rootReducer;

How can I access this field?

Trying to figure out an optimal way to create event handlers in React stateless components. I could do something like this:

    const myComponent = (props) =&gt; {
        const myHandler = (e) =&gt; props.dispatch(something());
        return (
            &lt;button onClick={myHandler}&gt;Click Me&lt;/button&gt;
        );
    }

The drawback here being that every time this component is rendered, a new &quot;myHandler&quot; function is created. Is there a better way to create event handlers in stateless components that can still access the component properties?

I have an object to store cached data which should look like this:

    private data = {
       &#39;some_thing&#39;: new DataModel(),
       &#39;another_name&#39;: new DataModel()
    }

I&#39;m trying to assign an empty object to it in the constructor:

    this.data = {}; // produces build error

Basically, i need to define the type of &quot;data&quot; field to say that it&#39;s going to have keys with random names and values of type DataModel. I&#39;ve tried to do this:

    private data: Object&lt;DataModel&gt;

But this is invalid. How would i specify a correct type?
