this controller table model (very new ror), 

class tablescontroller < applicationcontroller    before_action :set_table, only: [:show, :edit, :update, :destroy]    skip_before_filter  :verify_authenticity_token    # /tables    # /tables.json    def index      @tables = table.all    end      # /tables/1    # /tables/1.json    def show    end    # /tables/new    def new      @table = table.new    end    # /tables/1/edit    def edit    end    # post /tables    # post /tables.json    def create      @table = table.new(table_params)      respond_to |format|        if @table.save          format.html { redirect_to @table, notice: 'table  created.' }          format.json { render :show, status: :created, location: @table }          format.js {render :json => @table}        else          format.html { render :new }          format.json { render json: @table.errors, status: :unprocessable_entity  }          format.js {render :json =>@table.errors, status: :unprocessable_entity}        end      end    end    # patch/put /tables/1    # patch/put /tables/1.json    def update      respond_to |format|        if @table.update(table_params)          format.html { redirect_to @table, notice: 'table  updated.' }          format.json { render :show, status: :ok, location: @table }        else         format.html { render :edit }          format.json { render json: @table.errors, status: :unprocessable_entity }       end      end    end    # delete /tables/1   # delete /tables/1.json    def destroy      @table.destroy      respond_to |format|        format.html { redirect_to tables_url, notice: 'table  destroyed.' }        format.json { head :no_content }      end    end    private      # use callbacks share common setup or constraints between actions.      def set_table        @table = table.find(params[:id])      end        def table_params        params.permit(:num_seats, :restaurant_id, :x_loc, :y_loc, :available)      end  end

edit #2::

i have tried both using variable in-line css styling suggested javascript making html 5 canvas. css styling 1 pulling image each iteration in each loop, not positioning correctly.

i have debugging statements showing getting info.

<script>document.write("<%=table.x_loc%>")</script>

gives correct information, however,

<img id = "pic" style = "left: <%=table.x_loc%>; top:<%=table.y_loc%>;" src="<%=asset_path( 'overheadtable.jpg')%>">

is not positioning image correctly.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
